Description

The 74ACTQ657SC 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^TM technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO^TM output control and undershoot corrector of the 74ACTQ657SC in addition to a split ground bus or superior performance.
