description

These 12-bit buffers and line drivers are designed

specifically to improve both the performance and

density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and

transmitters.

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 12 outputs are in the

high-impedance state.

The outputs, which are designed to source or sink

up to 12 mA, include equivalent 25-W series

resistors to reduce overshoot and undershoot.

To ensure the high-impedance state during power

up or power down, OE should be tied to VCC

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking

capability of the driver.

The SN54ABT5402A is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ABT5402A is characterized for operation from –40°C to 85°C.
