The A port is designed to track V
CCA.
The B port is designed to track V
CCB
.
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.
The ST6G3237B is V
CCB
= 0V tolerant, achieving very low current consumption when the V
CCB
is grounded.
Description
The ST6G3237B is a dual supply low voltage
CMOS Level Translator for SD/MiniSD/T-Flash fabricated with sub-micron silicon gate and fivelayer metal wiring C
2
MOS 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.
