54ACTQ16540
16-Bit Inverting Buffer/Line Driver
with TRI-STATE^® Outputs
General Description
The ’ACTQ16540 contains sixteen inverting buffers with
TRI-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus-oriented transmitter/
receiver. The device is byte controlled. Each byte has sepa-
rate TRI-STATE control inputs which can be shorted together
for full 16-bit operation.
The ’ACTQ16540 utilizes NSC Quiet Series technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series^® features GTO^®
output control for superior performance.
Features
n Utilizes NSC FACT Quiet Series technology
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Separate control logic for each byte
n 16-bit version of the ’ACTQ540
n Outputs source/sink 24 mA
n Additional specs for multiple output switching
