74ACTQ16540
16-Bit Inverting Buffer/Line Driver with 3-STATE Outputs
General Description
The ACTQ16540 contains sixteen inverting buffers with 3-
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 sep-
arate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The ACTQ16540 utilizes Fairchild Quiet Series technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series fea-
tures GTO output control for superior performance.
Features
s Utilizes Fairchild FACT Quiet Series technology
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin output skew
s Separate control logic for each byte
s Outputs source/sink 24 mA
s Additional specs for multiple output switching
s Output loading specs for both 50 pF and 250 pF loads
