MOTOROLA MC74LCX543DW Low-voltage cmos octal latching transceiver Datasheet

$$ &"$
The MC74LCX543 is a high performance, non–inverting octal latching
transceiver operating from a 2.7 to 3.6V supply. 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 MC74LCX543 inputs to be
safely driven from 5V devices. The MC74LCX543 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,
LEBA, and OEBA inputs.

3. These AC parameters are preliminary and may be modified prior to release. The maximum AC limits are design targets. Actual performance
will be specified upon completion of characterization.
4. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGH–to–LOW (tOSHL) or LOW–to–HIGH (tOSLH); parameter
guaranteed by design.
