ON Semiconductor MC74VHCT138ADR2G Decoder/Demultiplexer

The MC74VHCT138ADR2G is an advanced high-speed CMOS 3-to-8 line decoder/demultiplexer fabricated by ON Semiconductor, a leading figure in energy-efficient innovations. This integrated circuit is designed to provide high-performance solutions for a variety of digital applications, particularly where low power consumption and fast switching are essential.

This decoder/demultiplexer is part of the VHCT family, which combines high noise immunity of CMOS with the speed of TTL devices. The MC74VHCT138ADR2G is designed to accept three binary weighted inputs (A0, A1, A2) and, when enabled, provides eight mutually exclusive active LOW outputs (Q0-Q7). The device features three enable inputs: two active LOW (E1, E2) and one active HIGH (E3). All outputs will be high unless E1 and E2 are LOW and E3 is HIGH.

One of the key attributes of the MC74VHCT138ADR2G is its compatibility with TTL. It can drive TTL inputs without the need for external resistors, simplifying design and reducing component count. This makes it an excellent choice for interfacing with legacy systems or devices that require TTL logic levels.

The MC74VHCT138ADR2G operates over a broad voltage range from 2.0V to 6.0V and features a low power consumption with a typical quiescent current of only 2 µA. This makes it suitable for battery-operated devices where power efficiency is crucial. Additionally, the device is capable of driving 10 LSTTL loads, which further enhances its utility in complex digital systems.

ON Semiconductor has packaged the MC74VHCT138ADR2G in a 16-pin SOIC package, which is ideal for space-constrained applications. The device also offers industrial-grade performance with a wide operating temperature range, ensuring reliability and stability across various environmental conditions.

This product is RoHS compliant, reflecting ON Semiconductor's commitment to environmental sustainability by reducing the presence of hazardous substances in electronic components.

Whether you're designing consumer electronics, communication devices, or complex computing systems, the MC74VHCT138ADR2G from ON Semiconductor is a robust and reliable choice that combines speed, power efficiency, and versatility.
