MICROCIRCUIT DATA SHEET Original Creation Date: 07/15/96 Last Update Date: 03/19/99 Last Major Revision Date: 03/08/99 MN54ACTQ245-X REV 2A0 Octal Bidirectional Transceiver With 3-State Inputs/Outputs General Description The ACQ/ACTQ245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications. Current sinking capability is 24 mA at both the A and B ports. The Transmit/Receiver (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (Active-HIGH) enables data from A ports to B ports; Receive (active-LOW) enables data from B ports to A ports. The Output Enable input, when HIGH, disables both A and B ports by placing them in a HIGH Z condition. The ACQ/ACTQ utilizes NSC Quiet Series technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series TM features GTO TM output control and undershoot corrector in addition to a split ground bus for superior performance.
