Description
The ST4G3235 is a dual supply low voltage
CMOS 4-bit bus buffer level translator fabricated
with sub-micron silicon gate and five-layer metal
wiring C
2
MOS 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, 1.8V/1.4V
and 2.5V/1.8V supply systems, it achieves high
speed operation while maintaining the CMOS low
power dissipation.
This IC is intended for one-way asynchronous
communication between data buses. The input
and output power down protections disable the
device when both power supply are down, so that
the buses are effectively isolated.
The input tolerant buffers allow to translate V
CCB
compatible signals and greater signals than V
CCB
up/down to V
CCA
and viceversa.
All inputs are equipped with protection circuits
against static discharge, giving them ESD
immunity and transient excess voltage.
