Working Principles

The SN74LVC2952APWR is designed to translate logic levels between two voltage domains. It utilizes low-voltage CMOS technology to achieve bidirectional voltage translation. The device consists of two sets of bidirectional buffers, each capable of translating signals from one voltage domain to the other.

When the output enable (OE) pin is high, the device is in an active state, allowing bidirectional data transfer. The input/output pins (I/O1A, I/O2A, I/O1B, I/O2B) are connected to the respective voltage domains (VCCA, VCCB). The voltage translation occurs based on the voltage levels applied to these pins.
