Description

The ST6G3238E 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 device 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 (on A-

side except CD and WP pins) and ±15kV on (B

side, CD and WP pins) ESD immunity and

transient excess voltage. See the section on

integrated ESD protections and resistors for more

information.
