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.
Features
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Combines the 245 and the 280 functions in one package
s 300 mil 24-pin slim dual-in-line package
s Outputs source/sink 24 mA
s ACTQ has TTL-compatible inputs
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code
