DESCRIPTION/ORDERING INFORMATION

This 18-bit universal bus driver is designed for 2.3-V

to 3.6-V VCC operation.

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

high. When LE is low, the A data is latched if the

clock (CLK) input is held at a high or low logic level. If

LE is low, 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 SN74ALVCF162835 has series damping

resistors in the device output structure that reduce

switching noise in 128-MB and 256-MB SDRAM

modules. Designed with a drive capability of ±18 mA,

this device is a midway drive between the

SN74ALVC162835 (±12 mA) and SN74ALVC16835

(±24 mA).
