Overview
The CD40109BPWRG4 is a CMOS Quad Low-to-High Voltage Level Shifter produced by Texas Instruments. This device is designed to handle level-shifting between different voltage levels without the need for a high-voltage supply (VDD) to be present before applying the low-voltage supply (VCC) or input signals. This flexibility makes it highly versatile in various electronic systems.
