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 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, 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 VCCB
compatible signals and greater signals than VCCB
up/down to VCCA and viceversa.
