Description
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Low-Voltage CMOS 16-Bit Latching Transceiver With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting) MC74LCX16543 The MC74LCX16543 is a high performance, non–inverting 16–bit latching transceiver operating from a 2.7 to 3.6V supply. The device is byte controlled. Each byte has separate control inputs which can be tied together for full 16–bit operation. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5V allows MC74LCX16543 inputs to be safely driven from 5V devices. The MC74LCX16543 is suitable for memory address driving and all TTL level bus oriented transceiver applications. For data flow from A to B with the EAB LOW, the A–to–B Output Enable (OEAB) must be LOW in order to enable data to the B bus, as indicated in the Function Table. With EAB LOW, a LOW signal on the A–to–B Latch Enable (LEAB) input makes the A–to–B latches transparent; a subsequent LOW–to–HIGH transition of the LEAB signal will latch the A latches, and the outputs no longer change with the A inputs. With EAB and OEAB both LOW, the 3–State B output buffers are active and reflect the data present at the output of the A latches. Control of data flow from B to A is symetric to that above, but uses the EBA, www.DataSheet4U.com LEBA, and OEBA inputs. LOW–VOLTAGE CMOS 16–BIT LATCHING TRANSCEIVER DT SUFFIX PL...
