General Description
The ACTQ657 contains eight non-inverting buffers with
TRI-STATE outputs and an 8-bit parity generator/checker. In-
tended for bus oriented applications, the device combines
the 鈥?45 and the 鈥?80 functions in one package.
The ACTQ utilizes NSC Quiet Series technology to guaran-
tee quiet output switching and improved dynamic threshold
performance. FACT Quiet Series

output
control and undershoot corrector in addition to a split ground
bus for superior performance.
