DESCRIPTION:
CMOS technology. The FCT82xT series bus interface regis-
ters are designed to eliminate the extra packages required to
buffer existing registers and provide extra data width for wider
address/data paths or buses carrying parity. The FCT821T
are buffered, 10-bit wide versions of the popular FCT374T
function. The FCT823T are 9-bit wide buffered registers with
Clock Enable (
interfacing in high-performance microprogrammed systems.
The FCT825T are 8-bit buffered registers with all the FCT823T
controls plus multiple enables (
user control of the interface, e.g.,
are ideal for use as an output port requiring high I
large capacitive loads, 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 high-impedance state.
