description
The ’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
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.
and OEAB both low, the 3-state

T o 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.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
