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.
