2-Bit Bidirectional Voltage-Level  
Translator with Auto Direction Sensing  
GENERAL DESCRIPTION  
FEATURES  
The SGM4556 is a 2-bit, non-inverting, bidirectional  
voltage-level translator which features two independent  
configurable power-supply lines. The A and B ports  
track the VCCA supply and VCCB supply respectively. The  
supply voltage range is 1.2V to 5.0V for A ports and  
1.65V to 5.5V for B ports. The device provides a  
bidirectional translation function between the different  
voltage nodes (including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V  
and 5V).  
Power Supply Voltage Range (VCCA ≤ VCCB  
A Ports: 1.2V to 5.0V  
)
B Ports: 1.65V to 5.5V  
Support VCCA or VCCB Isolation  
When VCCA or VCCB is Low, Device Enters  
Power-Down Mode  
OE Input Circuit Referenced to VCCA  
Support Partial-Power-Down Function  
Support Push-Pull Output  
Low Power Consumption  
The SGM4556 has an output enable (OE) function,  
which controls the outputs states. When OE goes low,  
all outputs enter into the high-impedance state. When  
VCCA is powered, OE has an internal pull-down current  
source. The OE should be connected to GND via a  
pull-down resistor, and the minimum resistor value is  
depended on the current source capability of the driver.

ESD Susceptibility  
ESD SENSITIVITY CAUTION  
This integrated circuit can be damaged if ESD protections are  
not considered carefully. SGMICRO recommends that all  
integrated circuits be handled with appropriate precautions.  
Failureto observe proper handlingand installation procedures  
can cause damage. ESD damage can range from subtle  
performance degradation tocomplete device failure. Precision  
integrated circuits may be more susceptible to damage  
because even small parametric changes could cause the  
device not to meet the published specifications.
