ST6G3238BE Dual supply level translator for SD/ MINISD/ T-FLASH With 8KV contact discharge ESD protection Features High speed: t = 4.4ns (Typ.) at T = 85C PD A V = 2.7V V = 1.8V CCB CCA Low power dissipation: I = I = 5A (Max.) at T = 85C CCA CCB A Balanced propagation delays: T T PLH PHL Power down protection on inputs and outputs TFBGA25 26 series resistor on A-Side EMI filter on B side Integrated pull-up and pull-down resistor on B side Description Operating voltage range: The ST6G3238BE is a dual supply low voltage V (Opr) = 1.4V to V CCA CCB CMOS Level Translator for SD/ MiniSD/ T-Flash V (Opr) = 1.4V to 3.6V CCB fabricated with sub-micron silicon gate and five- 2 layer metal wiring C MOS technology. Designed Latch-up performance exceeds 500mA for use as an interface between a 3.3V bus and a (JESD17) 2.5V or 1.8V bus in a mixed 3.3V/1.8V, 3.3V/2.5V ESD protection for card side (B port, CD and and 2.5V/1.8V supply systems, it achieves high WP pins) 8kV, IEC 61000-4-2 ESD or contact speed operation while maintaining the CMOS low discharge: power dissipation. The A port is designed to track HBM > 15kV (MIL STD 883 method 3015) V . The B port is designed to track V . CCA CCB ESD protection for A-port: This device is intended for two-way asynchronous HBM > 2kV (MIL STD 883 method 3015) communication between data buses and the R HS Compliant for TFBGA25 Package O 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 (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.
