Package

Description

The ST2G3236 is a dual supply, low-voltage

CMOS 2-bit bus transceiver produced with sub-

micron silicon gate and five-layer metal wiring

interface between a 3.3 V bus and a 2.5 V or

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

2.5 V/1.8 V 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 3 V bus,

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

All inputs are equipped with protection circuits to

protect against static discharge, giving them 2 kV

of ESD immunity and transient excess voltage.

MOS technology. Designed for use as an

QFN10 (1.8 mm x 1.4 mm)

with side series resistor
