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