FAST CMOS

BUS INTERFACE

LATCHES

DESCRIPTION:

The FCT8xxT series is built using an advanced dual metal

CMOS technology.

The FCT8xxT bus interface latches are designed to elimi-

nate the extra packages required to buffer existing latches

and provide extra data width for wider address/data paths or

buses carrying parity. The FCT841T are buffered, 10-bit wide

versions of the popular FCT373T function. They are ideal for

All of the FCT8xxT high-performance interface family can

drive large capacitive loads, while providing low-capacitance

bus loading at both inputs and outputs. All inputs have clamp

diodes to ground and all outputs are designed for low-capaci-

tance bus loading in high-impedance state.
