DESCRIPTION:
•
•
•
•
The FCT841T series is built using an advanced dual metal CMOS
technology.
The FCT841T 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 FCT841T 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.
