STMicroelectronics HCF4556BEY is a dual independent CMOS decoder/demultiplexer from the 4000B series, packaged in a 16-DIP (0.300", 7.62mm) through-hole configuration. Each of the two independent circuits functions as a 1-of-4 decoder/demultiplexer, featuring two select inputs (S0, S1) and an enable input (E). The HCF4556BEY supports a wide supply voltage range from 3V to 20V, with a dual supply voltage source. Its output current capabilities are 6.8mA for both high and low states. This component is suitable for applications in industrial control, data routing, and consumer electronics where reliable decoding and demultiplexing functions are required. The operating temperature range is -55°C to 125°C.
