description

The 'ABT162827A are noninverting 20-bit buffers composed of two 10-bit buffers with separate output-enable signals. For either 10-bit buffer, the two output-enable (1OE1\ and 1OE2\, or 2OE1\ and 2OE2\) inputs must both be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer are in the high-impedance state.

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

When V_CC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE\ should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABT162827A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT162827A is characterized for operation from -40°C to 85°C.
