STMicroelectronics 74LVQ138 3-to-8 Line Decoder/Demultiplexer
The 74LVQ138 is a high-speed CMOS 3-to-8 line decoder/demultiplexer integrated circuit produced by STMicroelectronics. This device is designed to be used in applications that require the conversion of a 3-bit binary input signal to one of eight mutually exclusive outputs. It is particularly suitable for implementing decoding and demultiplexing functions in a wide range of digital systems, from consumer electronics to industrial control systems.
The 74LVQ138 is part of STMicroelectronics' LVQ family, which is known for its low-voltage operation and high-speed performance. The device operates with a voltage supply ranging from 2.0V to 3.6V, making it compatible with low-voltage systems and ideal for battery-operated applications. Its low power consumption, combined with high noise immunity, ensures reliable operation even in challenging electrical environments.
Featuring three binary select inputs (A, B, and C), an enable input, and eight mutually exclusive outputs, the 74LVQ138 provides a compact and efficient solution for decoding applications. The enable input ensures that the outputs remain in a high-impedance state until the device is activated, thus preventing any spurious output activity and allowing for easy expansion with multiple devices.
Constructed with advanced silicon-gate CMOS technology, the 74LVQ138 offers fast propagation delay times and reduced power dissipation compared to traditional bipolar logic. Its 16-pin package makes it easy to integrate into a variety of circuit boards, and it is offered in several package types, including SO and TSSOP, to suit different assembly requirements.
The 74LVQ138 is a versatile component that can be used in a multitude of applications, such as address decoding for memory units, control signal generation, data routing, and more. Its ability to provide high-speed operation while maintaining low power consumption makes it an excellent choice for designers looking to optimize their digital systems for both performance and efficiency.
