description  
The ’ABT16952 are 16-bit registered transceivers  
that contain two sets of D-type flip-flops for  
temporary storage of data flowing in either  
direction. The’ABT16952canbeusedastwo8-bit  
transceivers or one 16-bit transceiver. 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 through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The SN54ABT16952 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABT16952 is characterized for operation from –40°C to 85°C.
