CD4099 8 bit Addressable Latch IC DIP-16 Package

The CD4099 is a CMOS 8-bit addressable latch IC in a DIP-16 package. It stores and outputs data on one of eight latches based on a 3-bit address input, making it ideal for expanding digital outputs in microcontroller projects.

Specifications

• Logic family: CMOS (CD4000 series)
• Number of latches: 8 (addressable)
• Address inputs: 3 (A0, A1, A2)
• Supply voltage: 3V to 15V DC
• Package: DIP-16 (Dual In-line Package, 16 pins)
• Output current: ±1.5 mA (typical)
• Operating temperature: -55°C to +125°C

Compatible with

• Arduino (Uno, Mega, Nano)
• ESP32 and ESP8266
• Raspberry Pi (via GPIO with level shifting)
• STM32
• Other 3.3V and 5V logic microcontrollers

What you can build with it

• Digital output expander for controlling 8 LEDs or relays using only 3 address lines
• Addressable memory register for storing and recalling 8 bits of data
• Multiplexed display driver for 7-segment or LED matrix projects
