The 74AC11138PWR is a high-performance, CMOS decoder/demultiplexer component designed and manufactured by Texas Instruments. This integrated circuit is part of the 74AC series, known for its advanced high-speed CMOS technology, which offers a blend of speed and power efficiency suitable for a wide range of applications.

Featuring dual 1-of-4 decoder/demultiplexer functionality, the 74AC11138PWR can operate as two individual 2-to-4 decoders or a single 3-to-8 decoder. It has two binary select inputs (A and B) and an enable input (G1) for each section. When the enable input is high, the decoder is active and the binary input data is decoded to activate one of the four mutually exclusive outputs. When the enable input is low, all outputs are forced low.

The device is housed in a TSSOP (Thin Shrink Small Outline Package) with 16 pins, which allows for a compact footprint on printed circuit boards. The 74AC11138PWR operates over a broad voltage range of 2V to 6V, providing versatile power supply compatibility, and features a typical power dissipation of 8µA, making it an energy-efficient choice for battery-operated devices.

With its fast propagation delay and output transition times, the 74AC11138PWR is ideal for high-speed memory decoders, data transmission systems, and various logic applications where efficient data distribution is needed. The device also includes additional features such as balanced propagation delays and output drive capability, which can drive up to 24mA at the output, ensuring reliable high-speed operation.

As with many Texas Instruments products, the 74AC11138PWR is characterized for operation from -40°C to 85°C, ensuring reliable performance in a wide range of environmental conditions. This makes it a suitable component for industrial, commercial, and even some automotive applications that require robust performance and longevity.

Overall, the 74AC11138PWR from Texas Instruments represents a reliable, efficient, and versatile solution for digital decoding and demultiplexing needs in advanced electronic systems.
