The CD40109BPWR is a logic level shifter IC that allows bidirectional voltage translation between different voltage domains. It operates by using a combination of MOSFETs and CMOS technology to ensure efficient and reliable signal transfer.
When an input signal from one voltage domain is applied to the corresponding input pin (A1, B1, C1, or D1), the CD40109BPWR translates the signal to the output pins (A2, B2, C2, or D2) in the target voltage domain. The outputs are non-inverting, meaning they maintain the same logic state as the inputs.
The CD40109BPWR can be used to interface different logic families or devices operating at different voltage levels, ensuring proper signal compatibility and communication between them.
