IDT74ALVC162334
FEATURES:
DESCRIPTION:
This 16-bit universal bus driver is built using advanced dual metal CMOS technology. Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode when the latch-enable (LE) input is low. When LE is high, the A data is latched if the clock (CLK) input is held at a high or low logic level. If LE is high, the A data is stored in the latch/flip-flop on the low-to-high transition of CLK. When OE is high, the outputs are in the high-impedance state. The ALVC162334 has series resistors in the device output structure which will significantly reduce line noise when used with light loads. This driver has been designed to drive 12mA at the designated threshold levels.
DRIVE FEATURES:
* Balanced Output Drivers: 12mA * Low Switching Noise
APPLICATIONS:
* SDRAM Modules * PC Motherboards * Workstations
