SN74AHC138PWR  

Encoders, Decoders, Multiplexers & Demultiplexers

The SN74AHC138PWR is a high-performance 3-to-8 line decoder/ demultiplexer integrated circuit (IC) manufactured by Texas Instruments. It is part of the 74AHC/AHCT series, which are advanced high-speed CMOS devices that offer excellent performance and low power consumption.

Description:

The SN74AHC138PWR is a 3-to-8 line decoder/demultiplexer that provides eight low-ohm outputs. It can be used to control multiple devices or circuits using a single input signal. The device has three select inputs (A, B, and C) that determine which of the eight outputs is active. When the select inputs are set to a specific combination, the corresponding output is activated, while the others are turned off.

Features:

1. 3-to-8 line decoder/demultiplexer
2. Active-low enable input (G) for enabling or disabling the device
3. Three select inputs (A, B, and C) for choosing the active output line
4. Eight low-ohm outputs for driving various loads
5. Advanced high-speed CMOS technology for excellent performance and low power consumption
6. Wide operating voltage range (2.0V to 6.0V)
7. High output current drive capability (up to 1.2A per output, depending on the supply voltage)
8. Available in a PowerSO-16 package

Applications:

1. Digital multiplexing and demultiplexing in communication systems
2. Control of multiple devices or circuits with a single input signal
3. Address decoding in memory applications
4. Signal distribution and routing in complex digital systems
5. Input/output expansion for microcontrollers and microprocessors
6. Logic control in industrial automation and control systems
7. Digital circuit design and prototyping

The SN74AHC138PWR is a versatile and high-performance IC that can be used in a wide range of digital applications, thanks to its advanced CMOS technology and features.
