STMicroelectronics M74HC353B1R Dual 4-Channel Analog Multiplexer/Demultiplexer
The M74HC353B1R is a high-speed CMOS device designed by STMicroelectronics to provide users with a dual 4-channel analog multiplexer/demultiplexer with a common select logic. This integrated circuit is part of the HC family, which means it combines silicon-gate CMOS technology with TTL functionality, offering the best of both worlds in terms of speed and power consumption.
With its wide operating voltage range of 2V to 6V, the M74HC353B1R is versatile and suitable for interfacing with both TTL and CMOS circuits. This makes it an ideal choice for various applications, including signal gating, chopper, modulator, demodulator, and CMOS logic implementation. Its low power consumption is a significant advantage in battery-operated and power-sensitive systems.
The device features two 4-channel multiplexers/demultiplexers with separate enable inputs (nE) and common binary address inputs (S0, S1). When the enable input is high, all the analog switches are turned off, which is useful for reducing power consumption when the device is not in active use. The low "on" resistance of the switch ensures minimal signal distortion, which is crucial for maintaining signal integrity in analog applications.
The M74HC353B1R is available in a DIP-16 plastic package, making it easy to integrate into a wide range of electronic circuits. Its pin configuration is designed for simplicity, with clearly marked inputs, outputs, and power supply pins, enabling designers to incorporate the device without hassle.
For protection, the device includes latch-up performance that exceeds 100mA per JESD 78, Class II, ensuring the reliability of the device under extreme conditions. Additionally, it has ESD protection, which safeguards the device from electrostatic discharges that could potentially damage the internal circuitry.
In summary, the M74HC353B1R from STMicroelectronics is a reliable and efficient solution for designers looking to implement dual 4-channel analog multiplexing/demultiplexing in their systems, with the added benefits of low power consumption, high-speed operation, and robust protection features.
