description
The
′BCT544 octal registered 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
transition of LEAB puts the A latches in the storage
mode. With CEAB and OEAB both low, the 3-state
B outputs are active and reflect the inverted 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.
The SN54BCT544 is characterized for operation
over the full military temperature range of – 55
°C
to 125
°C. The SN74BCT544 is characterized for
operation from 0
°C to 70°C.

A-to-B data flow is shown; B-to-A flow control is the same
except that it uses CEBA, LEBA, and OEBA.
