SN74AHCT158NG4: Quad 2-Line to 1-Line Data Selectors/Multiplexers

The SN74AHCT158NG4 is a high-performance, integrated circuit product from Texas Instruments, designed to provide optimal data selection and multiplexing capabilities. This quad 2-line to 1-line data selector/multiplexer IC is part of the 'AHCT' family, which means it features advanced high-speed CMOS technology with TTL-compatible inputs.

The device allows for the selection of one of two data inputs for each section by the common Select input (S). The data is transmitted to the output from the selected inputs when the Enable input (E\) is at a low logic level; when Enable is high, the outputs are in the high-impedance state. This feature allows for the use of these devices as translators in a mixed 3.3-V/5-V system environment.

The SN74AHCT158NG4 operates at a wide voltage range of 4.5V to 5.5V, making it suitable for interfacing with 5V logic systems. Its fast propagation delays and high noise immunity are characteristics of the AHCT technology, ensuring reliable performance in high-speed applications.

Key features of the SN74AHCT158NG4 include:

• Four independent 2-line to 1-line data selectors/multiplexers
• Wide operating voltage range of 4.5V to 5.5V
• Outputs can drive up to 15 LSTTL loads
• Low power consumption: 80-µA max ICC
• ±8-mA output drive at 5V
• Low input current of 1 µA max
• High-impedance state during power up and power down

This device comes in a 16-pin DIP (Dual In-line Package) making it easy to integrate into a wide range of digital systems. The SN74AHCT158NG4 is characterized for operation from -40°C to 85°C, ensuring that it can perform reliably in a variety of environmental conditions.

Whether you're designing digital communication systems, data routers, or need a reliable multiplexing solution for your application, the SN74AHCT158NG4 from Texas Instruments offers a versatile and high-performance option that engineers and designers can trust for their electronic projects.
