FEATURES

FUNCTIONAL DESCRIPTION

The 74F543 contains two sets of eight D-type latches, with separate

input and controls for each set. For data flow from A to B, for

example, the A-to-B Enable (EAB) input must be LOW in order to

enter data from A0 - A7 or take data from B0 - B7, 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 for the LEAB signal puts the

A latches in the storage mode and their 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.

• Combines74F245 and 74F373 type functions in one chip

• 8-bit octal transceiver with D-type latch

• Back-to-back registers for storage

• Separate controls for data flow in each direction

• A outputs sink 20 mA and source 3 mA

• B outputs sink 64 mA and source 15 mA

• 3-State outputs for bus-oriented applications

• Available in SSOP Type II package

DESCRIPTION

The 74F543 Octal Registered Transceiver 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 inputting and outputting in either direction of

data flow. The A outputs are guaranteed to sink 24 mA, while the

B outputs are rated for 64 mA.

3. Not more than one output should be shorted at a time. For testing I , the use of high-speed test apparatus and/or sample-and-hold

OS

techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting

of a HIGH output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any

sequence of parameter tests, I tests should be performed last.
