Working Principles

The SN74AC533PWRE4 is a logic level translator that allows seamless communication between devices operating at different voltage levels. It utilizes a combination of MOSFETs and CMOS technology to achieve bidirectional data flow.

When the output enable (OE) pin is low, the device is enabled, and the data from the input pins (D0-D7) is translated to the corresponding output pins (Q0-Q7). The latch enable (LE) pin controls the latching of the input data, ensuring stable output signals.

The device operates within a specified supply voltage range, translating logic levels from 0 V to VCC. It has a fast propagation delay time, enabling quick data transfer between voltage domains.
