Product Specification
PE926C31
Product Description
The PE926C31 is a high performance monolithic CMOS RS-422 line driver. Its operating supply range is 3.0 to 3.6 V, with an output signal overvoltage range of 0 - 6 V. The PE26C31 offers higher speed and lower power than other RS-422 driver types. It is packaged in a flat pack and is ideal for space applications. The PE926C31 is manufactured in Peregrine's patented Ultra Thin Silicon (UTSi(R)) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS.
Quad RS-422 Differential Line Driver Radiation Hardened

Electrostatic Discharge (ESD) Precautions
CQCQ+ C
When handling this UTSi device, observe the same precautions that you would use with other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified in Table 2. Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOSTM devices are immune to latch-up. Device Functional Considerations The PE926C31 operates at high switching speeds. In order to obtain maximum performance, it is crucial that pin 16 be supplied with a bypass capacitor to ground (pin 8).
