Working Principles

The CY74FCT16841CTPVCT utilizes a combination of MOSFETs and CMOS technology to achieve bidirectional voltage level translation. It employs a voltage divider network and level-shifting circuitry to ensure proper signal translation between two independent voltage domains.

When an input signal is applied to the A port, the IC detects the voltage level and translates it to the corresponding voltage level on the B port. Similarly, when a signal is applied to the B port, it is translated to the appropriate voltage level on the A port. This bidirectional translation capability enables seamless communication between different voltage systems.
