The HCF4585BEY is a versatile quad channel low power CMOS analog multiplexer/demultiplexer integrated circuit (IC) manufactured by STMicroelectronics. It is a digital multiplexer/demultiplexer that switches two or more digital input signals and multiplex them into a single output. It is designed to give a wide range of versatility in multiplexing and demultiplexing digital signals. The HCF4585BEY enables up to four digital input signals to be multiplexed into one single output port. It also has three enable signals that can be used to select which input is active. This can be used to provide different configurations with respect to the different inputs.The HCF4585BEY is an ideal analog multiplexer/demultiplexer for applications such as automotive diagnostic systems, portable electronics, power supply control, and motor control applications. It offers high switching speed and low power consumption, making it ideal for battery-powered applications. The HCF4585BEY has two operating modes: single device operations and cascade operations. In single device operations, the device is used to multiplex/demultiplex up to four input signals. Each of the four channels is individually selectable and can be routed to any output port. In cascade operations, two or more HCF4585BEY devices can be connected together to multiplex/demultiplex larger amounts of digital signals.The HCF4585BEY is designed to offer maximum flexibility for digital signal multiplexing. It features a wide voltage range of 2.4V to 6V and can handle input signal frequencies up to 200MHz. The device is also available in a 5V version with lower power consumption. The maximum switching speed is rated at 30MHz with propagation delays of less than 8ns. The working principle of the HCF4585BEY is fairly simple. There is a multiplexing logic that determines which of the four channels is active. Each channel is routed to the output pins according to the logic. The enable signals are then used to select which channel is routed to the output ports. The enable signals can be logic high or low, depending on the selection made. The HCF4585BEY is a versatile, low power digital multiplexer/demultiplexer that offers a wide range of options for multiplexing and demultiplexing digital signals. Its ability to handle higher input signal frequencies and wide voltage range makes it an ideal choice for applications such as automotive diagnostic systems, portable electronics, power supply control, and motor control applications. The simple working principle makes it easy to use and configure for various applications.
