概要

Description

The CD74HC138M96 is a high-speed CMOS 3-to-8 line decoder/demultiplexer. It is designed for use in data routing, memory address decoding, and data transfer applications. The device features three binary select inputs (A, B, C) and three enable inputs (G1, G2A, G2B), which allow for the selection of one of the eight outputs (Y0 to Y7) to be driven low while all others remain high. This active-low output configuration is ideal for decoding applications.
The CD74HC138M96 operates over a wide voltage range from 2V to 6V, making it suitable for various digital circuits. It is part of the 74HC family, known for high speed and low power consumption due to its CMOS technology.

Pinout

The CD74HC138M96 is a 3-to-8 line decoder/demultiplexer integrated circuit. It has a total of 16 pins. The primary function of this IC is to decode a 3-bit binary input into one of eight outputs, with each output corresponding to one of the input combinations. This makes it useful for applications requiring binary decoding or demultiplexing.
Here's a brief overview of its pin functions:
1. A0, A1, A2 (Pins 1, 2, 3): These are the address input pins. The 3-bit binary value applied here determines which one of the eight outputs (Y0 to Y7) will be activated.
2. G1, G2A, G2B (Pins 6, 4, 5): These are the enable pins. For the outputs to be active, G1 must be high, and both G2A and G2B must be low.
3. Y0 to Y7 (Pins 15, 14, 13, 12, 11, 10, 9, 7): These are the output pins. Only one of these pins will be low at any given time, based on the input address.
4. VCC (Pin 16): Power supply pin.
5. GND (Pin 8): Ground pin.
This IC is commonly used in digital circuits for address decoding and data routing tasks.
