Dual supply level translator for SD/ MINISD / T-FLASH Features - High speed: - t PD = 4.4ns (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 500m A (JESD17) ESD performance: - HBM > 2k V (MIL STD 883 method 3015); ROHS pliant for µTFBGA25 package µTFBGA25 TSSOP20 - - - - - Description The ST6G3237 is a dual supply low voltage CMOS Level Translator for SD/Mini SD/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 IC is intended for two-way asynchronous munication 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 ±2k V ESD immunity and transient excess voltage. - - - Order codes Part number ST6G3237TTR ST6G3237TBR Package TSSOP20 µTFBGA25 Packaging Tape and reel Tape and reel January 2007 Rev 1 1/17 .st. 17 Contents Contents 1 2 Logic diagram and truth table - - - - - - . . . 3 Pin settings -...
