DESCRIPTION:
The IDT54/74FCT800 series is built using an advanced
dual metal CMOS technology.
The IDT54/74FCT840 series 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 IDT54/74FCT841 is
a buffered, 10-bit wide version of the popular ‘373 function.
All of the IDT54/74FCT800 high-performance interface
family are designed for high-capacitance load drive capability,
while providing low-capacitance bus loading at both inputs
and outputs. All inputs have clamp diodes and all outputs are
designed for low-capacitance bus loading in the high-imped-
ance state.
