Low-Voltage CMOS 16-Bit
Latching Transceiver
With 5V–Tolerant Inputs and Outputs
(3–State, Non–Inverting)
The MC74LCX16543A 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 MC74LCX16543A
inputs to be safely driven from 5V devices. The MC74LCX16543A 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 symmetric to that above,
but uses the EBA, LEBA, and OEBA inputs.
