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.
