| ST6G3237 Dual supply level translator for SD/ MINISD / T-FLASH Features High speed: - tPD = 4.4ns (Max.) at TA = 85C - VCCB = 3.0V - VCCA = 2.3V Low power dissipation: - ICCA = ICCB = 5A (Max.) at TA = 85C Balanced propagation delays: - TPLH TPHL Power down protections on inputs and outputs 26 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 TFBGA25 package TFBGA25 TSSOP20 Description The ST6G3237 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 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.
