STMicroelectronics M74HCT4051RM13TR Analog Multiplexer/Demultiplexer

The M74HCT4051RM13TR is a high-performance CMOS 8-channel analog multiplexer/demultiplexer manufactured by STMicroelectronics, a leader in the semiconductor industry. This versatile integrated circuit (IC) is designed to function as an analog switch as well as a digital multiplexer, offering a wide array of applications in both the analog and digital domains.

With its silicon gate C2MOS technology, the M74HCT4051RM13TR ensures high-speed operation while maintaining the low power consumption that is characteristic of CMOS devices. This multiplexer/demultiplexer IC is compatible with the HCT family, and it has a pinout that is functionally compatible with the 4051 of the 4000B series, making it a suitable replacement for a variety of legacy systems as well as new designs.

One of the key features of the M74HCT4051RM13TR is its low "ON" resistance, which is typically around 70 ohms at 4.5V Vcc. This low resistance minimizes signal attenuation, ensuring that the integrity of the analog signal is preserved during switching. The device also boasts a low "OFF" leakage current, further enhancing its performance by reducing power loss and preventing unintended signal transmission when in the "OFF" state.

The M74HCT4051RM13TR operates over a wide voltage range, from 2V to 6V, which makes it suitable for interfacing with both TTL and CMOS logic levels. This flexibility is critical for mixed-voltage systems and allows for seamless integration into various circuit designs.

The device is offered in a small-outline package (SO), specifically in the 16-lead surface-mount package (RM13TR), which is ideal for space-constrained applications. The compact form factor combined with the device's robustness enables designers to create efficient, high-density circuit layouts without compromising on performance.

In summary, the M74HCT4051RM13TR from STMicroelectronics is a highly reliable and versatile component perfect for applications requiring the routing of analog or digital signals. Its low power consumption, compatibility with multiple logic families, and compact size make it an excellent choice for both modern and traditional electronic systems.
