Working Principles

The SN74AHCT16541DLG4 is a logic level shifter that facilitates bidirectional data transfer between two voltage domains. It utilizes non-inverting buffers to shift the logic levels of input signals from one domain to match the voltage levels of the other domain. The device operates at high speeds while consuming minimal power. It features 3-state outputs, which allow multiple devices to share a common bus without interfering with each other's signals. The integrated ESD protection ensures robustness against electrostatic
