ST1G3236 is a 1-bit dual supply bus transceiver with high speed operation and low power dissipation. It is designed for use as an interface between a 3.3V bus and a 2.5V or 1.2V bus. The device can be powered from 1.2V to 3.6V and supports two-way asynchronous communication. It features power-down protection on inputs and outputs, as well as protection against static discharge and transient excess voltage. The direction of data transmission is determined by input control.
