description  
These 16-bit buffers and bus drivers provide a  
high-performance bus interface for wide data  
paths.  
2OE1  
2OE2  
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 corresponding  
outputs are in the high-impedance state.  
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 SN54AHCT16540 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74AHCT16540 is characterized for operation from –40°C to 85°C.
