ST6G3238BE Dual supply level translator for SD/ MINISD/ T-FLASH With 8KV contact discharge ESD protection Features High speed: tPD = 4.4ns (Typ.) at TA = 85C VCCB = 2.7V VCCA = 1.8V Low power dissipation: ICCA = ICCB = 5A (Max.) at TA = 85C Balanced propagation delays: TPLH TPHL Power down protection on inputs and outputs 26 series resistor on A-Side EMI filter on B side Integrated pull-up and pull-down resistor on B side Operating voltage range: - VCCA (Opr) = 1.4V to VCCB - VCCB (Opr) = 1.4V to 3.6V Latch-up performance exceeds 500mA (JESD17) 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); ESD protection for A-port: HBM > 2kV (MIL STD 883 method 3015); ROHS Compliant for TFBGA25 Package TFBGA25 Description 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 Aside 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.
