SN74ABT162827A 具有三态输出的 20 位缓冲器/驱动器
SN74ABT162827A 描述
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-
series resistors to reduce overshoot and undershoot.
These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down
