Description

The 74HC138 3-to-8 line Decoder is a high-speed CMOS 3-to-8 line decoder/demultiplexer IC designed for efficient address decoding and data transmission. It accepts a 3-bit binary weighted address on inputs A0, A1, and A2, and outputs one active LOW signal, while the other seven outputs remain HIGH. The device features multiple enable inputs, including two active LOW enable inputs (E1, E2) and one active HIGH enable input (E3), providing flexibility in cascading and parallel expansion. When disabled, all outputs are HIGH, and when enabled, the device is active with the proper logic levels set on the enable inputs.
