CD40109 CMOS Quad Low-to-High Voltage Level Shifter IC DIP-16 Package

The CD40109 is a CMOS quad low-to-high voltage level shifter IC in a DIP-16 package. It converts low-voltage logic signals (e.g., 3.3V) to higher voltage levels (e.g., 5V or 15V), making it essential for interfacing different logic families in mixed-voltage projects.

Specifications

• Logic levels: Low-side input (VCC) from 3V to 18V, high-side output (VDD) from 3V to 18V
• Number of channels: 4 independent level shifters
• Package: DIP-16 (Dual In-line Package)
• Supply voltage range: 3V to 18V (both VCC and VDD)
• Operating temperature: -55°C to +125°C
• Propagation delay: Typically 100ns at 5V supply

Compatible with

• Arduino Uno, Mega, Nano
• ESP32 and ESP8266 boards
• Raspberry Pi (any model)
• STM32 microcontrollers
• Any 3.3V or 5V logic system

What you can build with it

• Interface a 3.3V sensor (e.g., BMP280) with a 5V Arduino board
• Drive a 5V relay module from a 3.3V ESP32 output
• Connect a 5V LCD display to a Raspberry Pi GPIO
