Description
The ST6G3238E is a dual supply low voltage CMOS level translator for SD / MiniSD / T-Flash fabricated with sub-micron silicon gate and fivelayer metal wiring C2MOS technology. Designed for use as an interface between a 3.3 V bus and a 2.5 V or 1.8 V bus in a mixed 3.3 V/1.8 V, 3.3 V/2.5 V and 2.5 V/1.8 V 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 3 V bus, while the A port interfaces with the 2.5 V and 1.8 V bus. All inputs are equipped with circuits to protect against static discharge, giving them 2 kV (on Aside except CD and WP pins) and 15 kV (on B side, CD and WP pins) ESD immunity and transient excess voltage. See the section on integrated ESD protection and resistors for more information.
