SN74HC138QPWRQ1

The Texas Instruments SN74HC138QPWRQ1 is a high-performance, high-density decoder/multiplexer that is part of the 74HC series of logic devices. It is designed to provide efficient and reliable signal routing in various applications.

Description:

The SN74HC138QPWRQ1 is a 1-of-8 decoder/multiplexer that decodes three binary-coded inputs (A0, A1, and A2) to select one of eight output lines (Y0 to Y7). It features three enable inputs (G1, G2A, and G2B) that control the overall operation of the device. When all enable inputs are high, the decoder is active, and the output corresponding to the binary input code is active. When any of the enable inputs are low, all outputs are in a high-impedance state.
