description

The SN54ABT16541 and SN74ABT16541A are noninverting 16-bit bufferscomposed of two 8-bit sections with separate output-enable signals.For either 8-bit buffer section, the two output-enable (1 and 1 or 2and 2) inputs must both be low for thecorresponding Y outputs to be active. If either output-enable inputis high, the outputs of that 8-bit buffer section are in thehigh-impedance state.

To ensure the high-impedance state during power up or power down, should be tiedto V_CC through a pullup resistor; the minimum value of theresistor is determined by the current-sinking capability of thedriver.

The SN54ABT16541 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74ABT16541A is characterized for operation from -40°C to85°C.
