74ACQ657SPC 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 SeriesTM technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTOTM output control and undershoot corrector in addition to a split ground bus or superior performance.
