IDT74ALVCF162835A

3.3V CMOS 18-BIT

UNIVERSAL BUS DRIVER

WITH 3-STATE OUTPUTS

DESCRIPTION:

This 18-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 high. 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 ALVCF162835A has series resistors in the device output structure

which will reduce switching noise in 128MB and 256MB SDRAM modules.

Designed with a drive capability of ±18mA, the ALVCF162835A is a mid-

way drive between the ALVC162835 (±12mA) and ALVC16835 (±24mA).

The ALVCF162835A is a faster version of the ALVCF162835 or

ALVC162835. It is suitable for PC133 applications and particularly SDRAM

Modules clocked at 133 MHz.
