Working Principles

The TC74VCX16841(EL,F) utilizes a combination of MOSFETs and CMOS technology to achieve bi-directional voltage level translation. The OE# pin controls the direction of data flow, enabling communication between devices operating at different logic levels. When the OE# pin is low, the IC acts as a bidirectional translator, allowing data to pass through in both directions. Conversely, when the OE# pin is high, the IC isolates the input and output sides, preventing any data transfer.
