description/ordering information
The ’ABT162827A devices 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-Ω series
resistors to reduce overshoot and undershoot.
