original creation date: 07/15/96 last update date: 03/19/99 last major revision date: 03/08/99 mn54actq245-x rev 2a0 microcircuit data sheet 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. ns part numbers 54actq245dmqb* 54actq245fmqb** 54ACTQ245LMQB*** industry part number 54actq245 prime die d245 controlling document 5962-92187 processing mil-std-883, method 5004 quality conformance inspection mil-std-883 5005 subgrp description temp ( c) o 1 static tests at +25 c 2 static tests at +125 c 3 static tests at -55 c 4 dynamic tests at +25 c 5 dynamic tests at +125 c 6 dynamic tests at -55 c 7 functional tests at +25 c 8a functional tests at +125 c 8b functional tests at -55 c 9 switching tests at +25 c 10 switching tests at +125 c 11 switching tests at -55 c 1
