description
The ′ABT32543 are 36-bit registered transceivers that contain two sets of D-type latches for temporary storage
of data flowing in either direction. These devices can be used as two 18-bit transceivers or one 36-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.

description (continued)
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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN54ABT32543 is characterized for operation over the full military temperature range of −55°C to 125°C.
The SN74ABT32543 is characterized for operation from − 40°C to 85°C.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 75 mils.
For more information, refer to the Package Thermal Considerations application note in the 1994 ABT Advanced BiCMOS Technology

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products

provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
