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, designed to interface between circuits operating at different voltage levels. It contains four independent level shifters, each capable of converting logic signals from a lower voltage (such as 3.3V) to a higher voltage (such as 5V) or vice versa. This IC is especially useful in mixed-voltage systems where logic circuits operating at different voltages need to communicate with each other, ensuring compatibility between modern low-voltage components and higher-voltage systems. Each of the four channels in the CD40109 can be used to shift a logic signal from low to high voltage, which makes it an ideal choice for applications where 3.3V logic needs to be interfaced with 5V TTL or CMOS systems, and vice versa. The IC works by translating the voltage levels in a reliable and noise-immune manner, making it suitable for use in digital systems where different voltage standards are present. Operating within a voltage range of 3V to 15V, the CD40109 ensures compatibility with both CMOS and TTL logic families. It is built using CMOS technology, providing low power consumption and high noise immunity, making it well-suited for high-performance and low-power designs.
