ON Semiconductor MC74HC138ADR2G Decoder/Demultiplexer

The ON Semiconductor MC74HC138ADR2G is a high-performance, 3-to-8 line decoder/demultiplexer designed for use in a wide range of digital applications. This integrated circuit is part of the high-speed CMOS family and is fabricated using silicon gate CMOS technology, ensuring minimal power consumption and high noise immunity characteristic of CMOS integrated circuits.

This device features three binary select inputs (A, B, and C) and eight mutually exclusive outputs (Y0 to Y7). The MC74HC138ADR2G is capable of decoding a three-bit binary code to one of eight output lines, making it ideal for applications where a specific signal line needs to be selected or activated from multiple options.

Additionally, the MC74HC138ADR2G includes three enable inputs: two active-low (E1, E2) and one active-high (E3). The enable inputs must be set to the appropriate logic levels to activate the decoding function. When the enables are in the correct state, the selected output will go low in response to the binary select inputs.

The device is offered in a small-outline 16-pin package (SOIC-16), making it suitable for space-constrained applications. It operates over a broad voltage range from 2 V to 6 V and can be used in systems requiring a wide range of supply voltages. With its extended temperature range of -55°C to 125°C, the MC74HC138ADR2G is also an excellent choice for industrial and automotive applications where reliability under extreme conditions is a necessity.

The MC74HC138ADR2G is a versatile component that simplifies design complexity and enhances system performance. It is commonly used in systems requiring address decoding, such as memory selection, data routing, and control signal generation, among others. With its high noise immunity and low power consumption, it represents a robust solution for modern digital electronics.

Whether you are designing consumer electronics, communication devices, or complex computing systems, the ON Semiconductor MC74HC138ADR2G provides a reliable and efficient decoding solution that can meet your technical requirements.
