Description

The ST6G3237 is a dual supply low voltage

CMOS Level Translator for SD/MiniSD/T-Flash

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.

The A port is designed to track VCCA. The B port

is designed to track VCCB.

This IC is intended for two-way asynchronous

communication between data buses and the

direction of data transmission is determined by

CMD-dir/DATA0-dir/DAT123-dir inputs. The B-port

interfaces with the 3V bus, the A-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.
