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.
