Working Principle

The M74HC4852RM13TR consists of eight independent single pole double throw (SPDT) switches with common output terminals. Each switch has two inputs (A & B) and an output. When Logic 0 is applied to the input, then the A input is connected to the output. When Logic 1 is applied to the input, then the B input is connected to the output. The switches are ideal for analog signal routing and are resistant to noise and interference for reliable operation. The device is designed for low power dissipation and high frequency operation. It is also compatible with TTL and CMOS logic levels for maximum flexibility when interfacing to logic circuits. Additionally, the low propagation delay of the device ensures fast and reliable switching, allowing it to be used in high-speed logic applications. In addition, the device requires only minimal external components, making it easy to integrate into a variety of applications.

Conclusion

The M74HC4852RM13TR is a versatile analog switch, multiplexer, and demultiplexer designed to provide reliable and efficient signal routing for a variety of applications. The device offers an extensive input voltage range, a low on-resistance for minimal signal distortion, and is compatible with TTL and CMOS logic levels. The device is also matched for channel-to-channel propagation delay, resulting in fast and reliable switching. With its ability to switch and multiplex analog signals between up to eight different sources, the M74HC4852RM13TR is the ideal choice for a wide range of applications including microprossessors and microcontrollers, wireless communication, data acquisition, and computer peripherals.
