description

The ′BCT543 octal transceiver contains two sets

of D-type latches for temporary storage of data

flowing in either direction. Separate latch-enable

(LEAB or LEBA) and output-enable (OEAB or

OEBA) inputs are provided for each register to

permit independent control in either direction of

data flow.

The A-to-B enable (CEAB) input must be low in

order to enter data from A or to output data from

B. If CEAB is low and LEAB is low, the A-to-B

latches are transparent; a subsequent low-to-high

mode. With CEAB and OEAB both low, the 3-state

B outputs are active and reflect the data present

at the output of the A latches. Data flow from B to

A is similar but requires using the CEBA, LEBA,

and OEBA inputs.
