The ’ABT2952A transceivers consist of two 8-bit  
back-to-back registers that store data flowing in  
both directions between two bidirectional buses.  
Data on the A or B bus is stored in the registers on  
the low-to-high transition of the clock (CLKAB or  
CLKBA) input provided that the clock-enable  
(CLKENAB or CLKENBA) input is low. Taking the  
output-enable (OEAB or OEBA) input low  
accesses the data on either port.

To ensure the high-impedance state during power  
up or power down, OE should be tied to V  
CC  
through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking  
capability of the driver.  
NC – No internal connection  
The SN54ABT2952A is characterized for  
operation over the full military temperature range  
of –55°C to 125°C. The SN74ABT2952A is  
characterized for operation from –40°C to 85°C.
