description

These 10-bit bus/MOS memory 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 (or ) 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 -55°C to 125°C. The SN74BCT2828B is characterized for operation from 0°C to 70°C.
