1 / 16 page June 2007 Rev 1 1/16 16 Features ■ High speed: –tPD = 6.2ns (Max.) at TA = 85°C –VCCB = 3.0V –VCCA = 2.3V ■ Low power dissipation: –ICCA = ICCB = 5µA (Max.) at TA = 85°C ■ Balanced propagation delays: –TPLH ≈ TPHL ■ Power down protections on inputs and outputs ■ 26Ω series resistor on A-Side ■ Operating voltage range: –VCCA (OPR) = 1.4V to VCCB –VCCB (OPR) = 1.4V to 3.6V ■ Latch-up performance exceeds 500mA (JESD17) ■ ESD performance: – HBM > 2kV (MIL STD 883 method 3015); ■ ROHS compliant for µTFBGA25 package Description The ST6G3237B 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. The ST6G3237B is VCCB = 0V tolerant, achieving very low current consumption when the VCCB is grounded. µTFBGA25 ST6G3237B Dual supply level translator for SD/ MINISD / T-FLASH www.st.com Figure 1.
