Description:
The CD4099 is a serial-input, parallel-output 8-bit addressable latch IC designed for data storage and control applications. It provides an efficient interface for handling serial data and offers flexible addressing and control features. With the ability to store and access data across 8 output channels, it is ideal for various digital systems requiring controlled data storage and retrieval. It supports bit addressing via A0, A1, and A2 inputs, allowing data to be written to specific bits. Additionally, the WRITE DISABLE function and Master Reset provide control flexibility for different operational needs.

The CD4099 is versatile, offering multiple package options, and operates over a wide supply voltage range of 3V to 18V.

Key Features:

• Serial Input, Parallel Output: Stores serial data across 8 output channels for efficient data handling.

• Bit Addressing: Enables addressing via A0, A1, and A2 inputs to store data in specific bits.

• Write Disable Function: Inhibits data entry when WRITE DISABLE is high, but allows all 8 outputs to remain readable.

• Master Reset: Resets all latch bits to logic "0" when both RESET and WRITE DISABLE are high.

• Demultiplexing Mode: Functions as a 1-of-8 demultiplexer when RESET is high and WRITE DISABLE is low.

• Wide Voltage Range: Operates between 3V to 18V supply voltages, offering flexibility in different applications.

• Multiple Package Options: Available in ceramic, plastic, and small-outline packages to suit various design needs.
