STMICROELECTRONICS ST6G3237BTBR

ST6G3237B
Dual supply level translator for SD/ MINISD / T-FLASH
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
µTFBGA25
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.
Description
The ST6G3237B 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.

1. CPD is defined as the value of the IC's internal equivalent capacitance which is calculated from the
operating current consumption without load. (Refer to Test Circuit). Average current can be obtained by the
following equation. ICC(opr) - CPD x VCC x fIN + ICC/16 (per circuit)
