Description

The ST2G3236 is a dual supply low voltage

CMOS 2-bit Bus Transceiver fabricated with sub-

micron silicon gate and five-layer metal wiring

C2MOS technology. Designed for use as an

interface between a 3.3V bus and a 2.5V or 1.8V

bus in a mixed 3.3V/1.8V, 3.3V/2.5V and

2.5V/1.8V supply systems, it achieves high speed

operation while maintaining the CMOS low power

dissipation.

This IC is intended for two-way asynchronous

communication between data buses and the

direction of data transmission is determined by

DIR inputs. The A-port interfaces with the 3V bus,

the B-port with the 2.5V and 1.8V bus.

All inputs are equipped with protection circuits

against static discharge, giving them 2kV ESD

immunity and transient excess voltage.
