description  
These 11-bit buffers and line drivers are designed  
specifically to improve both the performance and  
density of 3-state memory address drivers, clock  
drivers, and bus-oriented receivers and  
transmitters.

(TOP VIEW)  
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 11 outputs are in the  
high-impedance state. These devices provide  
inverted data.

The outputs, which are designed to source or sink  
up to 12 mA, include equivalent 25-series  
resistors to reduce overshoot and undershoot.

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.  
The SN54ABT5401 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABT5401 is characterized for operation from –40°C to 85°C.
