Working Principles

The FSTD16211MTD is a bidirectional logic level shifter that facilitates voltage translation between two different voltage domains. It utilizes a combination of MOSFETs and control circuitry to ensure seamless signal transfer while maintaining compatibility between devices operating at different logic voltage levels.

When an input signal is applied to either the A or B port, the internal circuitry detects the voltage level and adjusts the output accordingly. The bidirectional nature of the device allows for translation in both directions, enabling communication between devices with different logic voltage requirements.
