CD4099 8 bit Addressable Latch IC is a versatile CMOS logic integrated circuit designed for reliable digital data storage and output control. It allows individual addressing and latching of eight separate outputs using minimal control lines, making it ideal for memory expansion, I/O control, and digital system design. With low power consumption, wide operating voltage range, and excellent noise immunity, the CD4099 IC is widely used in embedded systems, industrial electronics, and educational projects.
Manufactured using advanced CMOS technology, the CD4099 ensures stable performance even in electrically noisy environments. Each output can be independently latched and held until updated, providing efficient control of multiple devices without continuous microcontroller intervention. This makes the CD4099 a preferred choice for designers seeking simplicity, flexibility, and energy efficiency.

How the CD4099 Addressable Latch Works
The CD4099 uses three address lines to select one of eight outputs. A single data input and enable signal control the selected output, allowing it to be set HIGH or LOW. Once latched, the output maintains its state independently, freeing the control system for other tasks. This efficient addressing scheme reduces pin usage and simplifies circuit design.
