74ACQ657
74ACTQ657
Quiet Series
Octal Bidirectional Transceiver with
8-Bit Parity Generator/Checker and 3-STATE Outputs
General Description
The ACQ/ACTQ657 contains eight non-inverting buffers
with 3-STATE outputs and an 8-bit parity generator/
checker. Intended for bus oriented applications, the device
combines the 245 and the 280 functions in one package.
The ACQ/ACTQ utilizes Fairchild Quiet Series
technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series fea-
tures GTO
output control and undershoot corrector in
addition to a split ground bus or superior performance.
