description

These 12-bit buffers and line drivers are designed specifically toimprove both the performance and density of 3-state memory addressdrivers, clock drivers, and bus-oriented receivers and transmitters.

The 3-state control gate is a 2-input AND gate with active-lowinputs so that if either output-enable ( or) input is high, all 12 outputs are in thehigh-impedance state. These devices provide inverted data.

The outputs, which are designed to source or sink up to 12 mA,include equivalent 25-series resistors to reduce overshoot and undershoot.

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 SN54ABT5403 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74ABT5403 is characterized for operation from -40°C to85°C.
