The ST6G3238BE 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 3.3V 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 Bport 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.主要特性
- ESD protection for card side (B port, CD and WP pins) ±8kV, IEC 61000-4-2 ESD or contact discharge:
HBM > ±15kV (MIL STD 883 method 3015); - Latch-up performance exceeds 500mA (JESD17)
- ROHS Compliant for µTFBGA25 Package
- ESD protection for A-port:
HBM > ±2kV (MIL STD 883 method 3015); - Integrated pull-up and pull-down resistor on B side
- EMI filter on B side
- High speed: tPD = 4.4ns (Typ.) at TA = 85°C VCCB = 2.7V VCCA = 1.8V
- Balanced propagation delays: TPLH ≈ TPHL
- Low power dissipation:
ICCA = ICCB = 5µA (Max.) at TA = 85°C - 26Ω series resistor on A-Side
- Operating voltage range:
VCCA (Opr) = 1.4V to VCCB VCCB (Opr) = 1.4V to 3.6V - Power down protection on inputs and outputs
- ESD protection for card side (B port, CD and WP pins) ±8kV, IEC 61000-4-2 ESD or contact discharge:
