Product Introduction

Overview

The ST1G3236DTR is a 1-bit dual supply bus transceiver level translator produced by STMicroelectronics. This device is fabricated using sub-micron silicon gate and five-layer metal wiring C2MOS technology. It is designed for use in mixed supply systems, enabling high-speed operation between different voltage levels such as 3.3V, 2.5V, and 1.2V. The ST1G3236DTR is ideal for two-way asynchronous communication between data buses, with the direction of data transmission controlled by the DIR input.
