Working Principles

The CD74HCT541M96E4 utilizes a combination of CMOS technology and level-shifting circuitry to achieve bidirectional voltage translation. It operates by monitoring the input voltage levels and translating them to the corresponding output voltage levels based on the logic family compatibility.

When the OE# pin is low, the IC is enabled, and the data can flow bidirectionally between the input and output pins. When the OE# pin is high, the IC is disabled, and the outputs are in a high-impedance state.
