74ACTQ544 General Description

The ACQ/ACTQ544 is an inverting octal transceiver containing two sets of D-type registers for temporary storage of data flowing in either direction. Separate Latch Enable and Output Enable inputs are provided for each register to permit independent input and output control in either direction of data flow. The 544 inverts data in both directions.

The ACQ/ACTQ utilizes Fairchild FACT Quiet Series^TMtechnology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO^TM output control and undershoot corrector in addition to a split ground bus for superior performance.
