HCF4099B, an 8-bit addressable latch, is a serial-input, parallel output storage register that can perform a variety of functions.
The HCF4099B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, available in DIP and SOP packages. It functions as an 8-bit addressable latch, serving as a serial-input, parallel-output storage register. The device can also perform as a demultiplexer and includes a master reset input to clear all bits to a logic "0" level.
