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 outputs are also in  
the high-impedance state during power-up and  
power-down conditions. The outputs remain in the  
high-impedance state while the device is powered  
down.

The outputs, which are designed to source or sink  
up to 12 mA, include 33-series resistors to  
reduce overshoot and undershoot.

The SN54BCT2828A is characterized for opera-  
tion over the full military temperature range of  
− 55°C to 125°C. The SN74BCT2828B is  
characterized for operation from 0°C to 70°C.
