STMicroelectronics M74HCT4052TTR Analog Multiplexer/Demultiplexer

The M74HCT4052TTR from STMicroelectronics is a high-performance, silicon-gate CMOS dual 4-channel analog multiplexer/demultiplexer with logic-level conversion capability. This versatile component is designed to function as a two-bit digital multiplexer allowing the selection of one out of four channels to be turned on and connect a single output line. It can also operate as a demultiplexer, distributing a single input signal to one of the four outputs.

This integrated circuit is pin-compatible with the standard 4052 series, but it has several enhancements that make it a robust choice for modern electronic applications. The M74HCT4052TTR operates at a wide voltage range from 2V to 6V, making it suitable for interfacing with both TTL and CMOS digital logic levels. Furthermore, it features low "ON" resistance and low "OFF" leakage current, ensuring minimal signal distortion and high fidelity in signal switching applications.

The device comes in a TSSOP-16 package, which is known for its small footprint and optimal space-saving capabilities on printed circuit boards (PCBs). The M74HCT4052TTR is characterized for operation from -55°C to +125°C, making it reliable in a broad range of environmental conditions. This temperature range, along with its low power consumption, makes it an excellent choice for automotive, industrial, and telecommunication systems where performance and durability are critical.

The M74HCT4052TTR includes additional features such as an inhibit function to disable all channels, and it also provides break-before-make switching action, which prevents momentary shorting when switching between channels. It's a suitable component for analog signal routing in applications such as data acquisition systems, signal multiplexing, audio/video switching, and any other system that requires high-speed, low-resistance switching of analog signals.

With its robust design and versatile functionality, the STMicroelectronics M74HCT4052TTR is an essential building block for designers looking to create complex multiplexing systems without compromising on performance and reliability.
