general description the max14930Cmax14932 are a family of 4-channel, digital isolators utilizing maxims proprietary process technology. for applications requiring 5kv rms of isolation, see the max14934Cmax14936. the max14930C max14932 family transfers digital signals between circuits with different power domains at ambient temperatures up to +125c. the max14930Cmax14932 family offers all three possible unidirectional channel configurations to accommodate any 4-channel design; including spi, rs-232, rs-485, and digital i/o applications. for applications requiring bidirectional channels, such as i 2 c, see the max14933. devices are available with data rates from dc up to 1mbps, 25mbps, or 150mbps. each device is also available in either a default high or default low configuration. the default is the state an output goes to when its input is unpowered. see the ordering information and selector guide for the suffixes associated with each option. independent 1.71v to 5.5v supplies on each side of the isolator also make the devices suitable for use as level translators. the max14930Cmax14932 are available in both a 16-pin wide body (10.3mm x 7.5mm) and narrow body (9.9mm x 3.9mm) soic package. all devices are rated for operation at ambient temperatures of -40c to +125c. beneits and features robust galvanic isolation of digital signals ? withstands up to 3.75kv rms for 60s (v iso ) ? constinuously withstands 443v rms ( v iowm ) ? 630v p repetitive peak voltage ( v iorm ) ? withstands 10kv surge per iec 61000-4-5 interfaces directly with most micros and fpgas ? accepts 1.71v to 5.5v supplies many options support broad applications ? 3 data rates (1mbps, 25mbps, 150mbps) ? 3 channel direction coniguration ? 2 output default states (high or low) ? 2 packages (4mm or 8mm creepage and clearance) low power consumption at high data rates at 1.8v: ? 2.5 ma per channel typical at 1mbps ? 5.25 ma per channel typical at 100mbps at 3.3v: ? 2.6 ma per channel typical at 1mbps ? 7.1 ma per channel typical at 100mbps safety regulatory approvals (see safety regulatory approvals ) ul according to ul1577 cul according to csa bulletin 5a vde 0884-10 (pending) applications fieldbus communications for industrial automation isolated spi, rs-232, rs-485/rs-422 general multichannel isolation applications battery management medical systems ordering information and selector guide appears at end of data sheet. 19-7066; rev 6; 5/16 max14930Cmax14932 4-channel, 2.75kv rms and 3.75kv rms digital isolators ina1 max14930 ina2 ina3 ina4 gnda gndb v dda v ddb outb1 enb outb2 outb3 outb4 outb1outb2 outb3 inb1 ina1 max14931 ina2 ina3 outa1 enb ena gnda gndb v dda v ddb outb1outb2 inb1 inb2 ina1 max14932 ina2 outa1 outa2 enb ena gnda gndb v dda v ddb functional diagram evaluation kit available downloaded from: http:///

max14930Cmax14932 4-channel, 2.75kv rms and 3.75kv rms digital isolators www.maximintegrated.com maxim integrated 19 detailed description the max14930Cmax14932 are a family of 4-chan - nel digital isolators. the max14930Cmax14932 family transfers digital signals between circuits with different power domains. the devices are rated for up to 3.75kv rms isolation voltage for 60 seconds. this family of digital isolators offers low-power operation, high electromagnetic interference (emi) immunity, and stable temperature performance through maxims proprietary process technology. the devices isolate different ground domains and block high-voltage/ high-current transients from sensitive or human interface circuitry. the devices offer three unidirectional channel configurations for design convenience. the max14930 features four channels transferring digital signals in one direction for applications such as isolated digital i/o. the max14931 has three channels transmitting data in one direction and one channel transmitting in the opposite direction, making it ideal for applications such as isolated spi and rs-485 communication. the max14932 provides further design flexibility with two channels in each direction for isolated rs-232 or other applications. devices are available with data rates from dc up to 1mbps (a/d versions), 25mbps (b/e versions), or 150mbps (c/f versions). each device can also be ordered with default- high or default-low outputs. this is the state an output will go to when the input side of the device is unpowered. the devices have two supply inputs, v dda and v ddb , that independently set the logic levels on either side of the device. v dda and v ddb are referenced to gnda and gndb, respectively. the max14930Cmax14932 family also features a refresh circuit to ensure output accuracy when an input remains in the same state indefinitely. digital isolation the max14930Cmax14932 family provides galvanic isolation for digital signals that are transmitted between two ground domains. up to 630v peak of continuous isolation is supported, as well as transient differences of up to 3.75kv rms for up to 60 seconds. level shifting the wide supply voltage range of both v dda and v ddb allows the max14930Cmax14932 family to be used for level translation in addition to isolation. v dda and v ddb can be independently set to any voltage from 1.71v to 5.5v. the supply voltage sets the logic level on the corresponding side of the isolator. unidirectional channels each channel of the max14930Cmax14932 is unidirectional; it only passes data in one direction, as indicated in the functional diagram. each device features four unidirectional channels that operate independently with guaranteed data rates from dc up to 1mbps (a/d versions), 25mbps (b/e versions), or 150mbps (c/f versions). the output driver of each channel is push-pull, eliminating the need for pullup resistors. the outputs are able to drive both ttl and cmos logic inputs. startup and undervoltage lockout the v dda and v ddb supplies are both internally monitored for undervoltage conditions. undervoltage events can occur during power-up, power-down, or during normal operation due to a sagging supply voltage. when an undervoltage condition is detected on either supply, all outputs go to their default states regardless of the status of the inputs ( table 1 ). figure 2 through figure 5 show the behavior of the outputs during power-up and power-down. downloaded from: http:///
