The CD74AC138M is a high-speed CMOS Logic 3-to-8 line decoder/demultiplexer designed and manufactured by Texas Instruments. This integrated circuit is ideal for hardware designers and electrical engineers looking for a reliable solution in applications that require the distribution of a single input signal into one of several output lines.
Featuring advanced silicon-gate CMOS technology, the CD74AC138M provides users with significant power savings over its TTL counterparts without sacrificing speed. This makes it suitable for battery-operated and power-sensitive devices. The device ensures glitch-free output transitions due to its balanced propagation delays and symmetrical output impedance.
Key Features:
- Logic Family: AC
- Logic Type: 3-to-8 Line Decoder/Demultiplexer
- Supply Voltage Range: 2V to 6V
- Operating Temperature Range: -55°C to 125°C
- Package / Case: SOIC-16

The CD74AC138M is capable of demultiplexing up to eight distinct output lines from a single input signal. It features three binary select inputs (A, B, and C), an enable input, and eight mutually exclusive outputs. When the enable input is high, all outputs are forced to a low state. When enabled, the binary input signals select one of the eight output lines to carry a high state, effectively routing the input to the selected output.
This device is typically used in a wide range of applications, including data multiplexing, signal routing, and memory address decoding. The CD74AC138M is offered in a slim outline integrated circuit (SOIC) package, which is designed for space-saving on PCBs and is compatible with standard surface-mount technology (SMT) processes.
With its robust design and high functionality, the Texas Instruments CD74AC138M is a versatile component that enhances the performance and efficiency of electronic systems across various sectors.
Applications:
- Data multiplexing
- Signal routing
- Memory address decoding
- Control systems
