Octal Registered Transceiver with TRI-STATE Outputs
General Description
The 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 ACTQ544 utilizes NSC's FACT TM Quiet Series technology to guarantee quiet output
switching the improved dynamic threshold performance. FACT Quiet series features GTO
output control and undershoot corrector in addition to split ground bus for superior
performance.
