description
The
′ABT543 octal transceivers contain 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 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.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74ABT543 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54ABT543 is characterized for operation over the full military temperature range of – 55
°C to 125°C. The
SN74ABT543 is characterized for operation from – 40
°C to 85°C.
