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
V_CCA. The B port is designed to track V_CCB.
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.
