and 200V per Machine Model

DESCRIPTION

The 74LVT543 is a high-performance BiCMOS product designed for

VCC operation at 3.3V.

This device contains two sets of D-type latches for temporary

storage of data flowing in either direction. Separate Latch Enable

(LEAB, LEBA) and Output Enable (OEAB, OEBA) inputs are

provided for each register to permit independent control of data

transfer in either direction. The outputs are guaranteed to sink

64mA.

FUNCTIONAL DESCRIPTION

The 74LVT543 contains two sets of eight D–type latches, with

separate control pins for each set. Using data flow from A to B as an

example, when the A-to-B Enable (EAB) input and the A-to-B Latch

Enable (LEAB) input are Low the A-to-B path is transparent. A

subsequent Low-to-High transition of the LEAB signal puts the A

data into the latches where it is stored and the B outputs no longer

change with the A inputs. With EAB and OEAB both Low, the

3-State B output buffers are active and display the data present at

the outputs of the A latches.

Control of data flow from B to A is similar, but using the EBA, LEBA,

and OEBA inputs.
