STMicroelectronics HCF4067BM1: 16-Channel Analog Multiplexer/Demultiplexer IC

The HCF4067BM1 is a versatile integrated circuit from STMicroelectronics designed for efficient channel multiplexing and demultiplexing in a variety of electronic applications. This monolithic chip is a high-performance CMOS 16-channel analog multiplexer/demultiplexer that offers a direct interface with TTL and CMOS. Its primary function is to control analog voltages that may vary across the full analog signal range (VDD - VEE).

The device features 16 single-ended channels that can be controlled by four binary control inputs (A, B, C, and D). These inputs determine which channel is selected when the device is in multiplexer mode. In demultiplexer mode, the single input can be routed to any of the 16 output channels, again based on the state of the binary control inputs. The HCF4067BM1 can also be used as a function generator, which makes it a highly versatile component for various applications.

With its low ON impedance and very low OFF leakage current, the HCF4067BM1 ensures minimal signal distortion. The chip operates over a wide range of supply voltages from 10V to 20V, making it suitable for many power environments. Additionally, the HCF4067BM1 features an "inhibit" function which allows the user to turn off all channels and thus minimize power consumption when the device is not in use.

STMicroelectronics has designed the HCF4067BM1 with ESD protection, ensuring robustness and reliability of the component in the face of electrostatic discharges. The chip comes in a compact SOIC-24 package, which is ideal for space-constrained applications that require a large number of channels to be multiplexed.

The HCF4067BM1 is commonly used in signal gating, data acquisition systems, analog-to-digital conversion, communication systems, and many other applications that require a high degree of channel control. Its ability to work effectively across a wide range of operating conditions and its compatibility with various logic families make it a go-to choice for designers and engineers looking for a reliable multiplexing/demultiplexing solution.
