ON Semiconductor MC74LCX138DTR2G Decoder/Demultiplexer

The MC74LCX138DTR2G is a high-performance, low-voltage 3-to-8 line decoder/demultiplexer integrated circuit produced by ON Semiconductor, a leading manufacturer in the industry. This device is designed to be used in applications that require the decoding or demultiplexing of signals, making it an essential component for a wide range of electronic systems.

Constructed with advanced silicon gate CMOS technology, the MC74LCX138DTR2G offers optimal performance while operating at a lower power supply voltage, ranging from 2.3V to 3.6V. This makes it particularly suitable for battery-operated and portable devices where power efficiency is crucial. It also provides 5V tolerant inputs, which allow the device to be used in mixed-voltage environments, ensuring compatibility with older 5V systems.

The device features three binary select inputs (A, B, and C), an enable input, and eight mutually exclusive outputs. When the enable input is activated, the binary select inputs determine which one of the eight outputs will be low, providing a decoded demultiplexing function. The high-impedance state during power-down ensures minimal power consumption when the device is not in use.

The MC74LCX138DTR2G is characterized by its fast propagation delay and output transition times, making it an excellent choice for high-speed applications. Additionally, the device has a robust output drive capability, which can source or sink 24 mA at 3.0V, allowing it to drive larger loads if required.

ON Semiconductor's commitment to quality is reflected in the MC74LCX138DTR2G's design, which includes over-voltage tolerance and noise immunity features. This ensures reliable operation even in electrically noisy environments. The device is available in a TSSOP-16 package, providing a compact footprint suitable for space-constrained applications.

Whether it's used in computing systems, communication devices, or consumer electronics, the MC74LCX138DTR2G by ON Semiconductor offers designers a versatile and energy-efficient solution for decoding and demultiplexing needs.
