The FCT8xxT series is built using an advanced dual metal CMOS technology. The FCT8xxT bus interface latches are designed to eliminate 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 use as an output port requiring high IOL/IOH. 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-capacitance bus loading in high-impedance state.
This document describes the IDT54/74FCT841AT/BT/CT/DT series of fast CMOS bus interface latches. These devices are designed to eliminate extra packages required for buffering existing latches and provide data width expansion for wider address/data paths or buses carrying parity.
The latches utilize an advanced dual metal CMOS technology and feature true TTL input and output compatibility with low leakage currents. They are available in various packages including DIP, SOIC, SSOP, QSOP, CERPACK, and LCC, suitable for both commercial and military temperature ranges.
