These 10-bit buffers or bus drivers provide a  
high-performance bus interface for wide data  
paths or buses carrying parity.

The 3-state control gate is a 2-input AND gate with  
active-low inputs so that if either output-enable  
(OE1 or OE2) input is high, all ten outputs are in  
the high-impedance state. The ’ABT2827 provide  
true data at their outputs.

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 outputs, which are designed to source or sink  
up to 12 mA, include equivalent 25-series  
resistors to reduce overshoot and undershoot.  
The SN54ABT2827 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABT2827 is characterized for operation from –40°C to 85°C.
