Overview
The CD40109BNSR is a versatile and robust level-shifting circuit produced by Texas Instruments. Unlike other low-to-high level-shifting circuits, the CD40109B does not require the presence of the high-voltage supply (VDD) before applying the low-voltage supply (VCC) or input signals. This component is designed to operate with a wide range of supply voltages and input signals, making it highly flexible for various applications.
