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.
