descriptionThe ’ABT16543 16-bit registered transceivers
contain two sets of D-type latches for temporary
storage of data flowing in either direction. The
’ABT16543 can be used as two 8-bit transceivers
or one 16-bit transceiver. 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 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 SN54ABT16543 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT16543 is characterized for operation from –40°C to 85°C.
