ST16C32245TBR-E

Translators, Level Shifters Overview

The ST16C32245TBR-E is a 14-bit dual supply bus transceiver and level translator manufactured by STMicroelectronics. It facilitates asynchronous communication between buses operating at different voltage levels, specifically interfacing a 3 V A-port with a 2.5 V or 1.8 V B-port. The device operates within a VCCA range of 2.3 V to 3.6 V and a VCCB range of 1.65 V to 2.7 V. It features balanced propagation delays, power-down protection on inputs and outputs, and integrated 26 Ω series resistors on the A-side outputs. The component includes two dedicated I2C lines for level translation and provides bus hold functionality on data inputs.
