The CD74AC138M96E4 is a signal switches, multiplexers, and decoders integrated circuit (IC) produced by Texas Instruments. It is a three-state decoder/demultiplexer with low on-state resistance at 1.5 ohms. It was designed to provide decoding and demultiplexing of digital signals with improved signal and power switching performance.

The CD74AC138M96E4 has a 9-bit addressable input that supports up to 512 data outputs. Depending on the address of an incoming signal, the device will route it to the appropriate output. This makes the CD74AC138M96E4 ideal for applications requiring a compact device for addressing and routing digital signals, such as multi-channel data transmission and video distribution systems.

The CD74AC138M96E4 operates from a single 2.0V to 7.0V power supply, drawing 270mA maximum current. It is also ESD-protected with a 1.5KV human body model (HBM) rating, 0.5KV power lines, and 0.3KV PC card/IC pins. Its package is an extended-temperature SO-42P with a 75um pitch.

The CD74AC138M96E4 is a popular choice for its balance of performance, price, and power consumption. It is used in a number of areas, including industrial control, telecom, and audio applications. Due to its low power consumption, the CD74AC138M96E4 is ideal for portable devices that require a low-power signal routing solution.

The CD74AC138M96E4 is a CMOS IC, using a combination of logic and switching transistors to implement its functionality. Its architecture utilizes two sets of polarity-controlled power MOSFETs to create either an open or short circuit connection between the output node and ground, depending on the logic level applied to the control inputs. This allows the device to rapidly switch between high- and low-current signals.

The CD74AC138M96E4 also utilizes an internal diode network and capacitors on each output node to maintain a stable switching transition from high- to low-logic states. This ensures that each output follows a low jitter and low latency timing structure, making it suitable for applications requiring tight control over output signals.

Overall, the CD74AC138M96E4 is a high-performance signal switch and multiplexer device, ideal for applications requiring fast, reliable switching and routing of digital signals. With its combination of low power consumption and high-speed switching, the device is preferred in low-power applications, such as portable audio devices and multi-channel data transmission systems.
