The M74HC42RM13TR is a versatile part belonging to the Logic - Signal Switches, Multiplexers, Decoders category of electronic devices. It is a quad analog multiplexer and demultiplexer with logarithmic response, manufactured by ST Microelectronics and is available in the SOT23-6L (Thin Package) form factor.

This device is intended for use in applications such as data acquisition systems, signal switching, signal routing, audio and video networks and other display or signal processing equipment. It is particularly suitable for applications which require an amplitude-independent signal transmission.

The M74HC42RM13TR has four signal inputs, one enable input and eight signal outputs. It has a signal transmission speed of up to 1 Mbps and can be operated with a supply voltage range of 2.0VDC to 3.6VDC. It also has an integrated low-power CMOS technology to reduce power consumption.

The working principle of M74HC42RM13TR is based on analog multiplexing. In multiplexing, the same signal is switched to different selections of receivers. In case of the M74HC42RM13TR, the three of its four input signals are connected to a particular selection of receivers. The fourth input signal allows for a single selection of the receiver. The enable input activates the multiplexing process, and the signal at the input is connected to the selection of receivers according to the conditions set by the enable signal. The signal then passes through the respective receivers and then is transmitted out of the device through the signal outputs.

The M74HC42RM13TR is suitable for a variety of applications, including data acquisition systems, signal switching, signal routing, audio and video networks and other display or signal processing equipment. It is also suitable for low-frequency applications such as receivers, amplifiers and signal conditioning systems. Moreover, it has a low-power transmit and receive timing response and is rugged enough to handle the wide temperature range from -40°C to +85°C.

Overall, the M74HC42RM13TR from ST Microelectronics is an effective and sophisticated device belonging to the Logic - Signal Switches, Multiplexers, Decoders category. Its logarithmic response and versatile design make it a suitable choice for a variety of applications which require an amplitude-independent signal transmission.
