SGM4556
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.
● -40℃ to +85℃ Operating Temperature Range
● Available in Green XTDFN-1.4×1-8L and SOT-23-8
Packages
APPLICATIONS
Universal Asynchronous Receiver/Transmitter (UART)
General Purpose I/O (GPIO)
The SGM4556 is available in Green XTDFN-1.4×1-8L
and SOT-23-8 packages. It operates over an ambient
temperature range of -40℃ to +85℃.

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.
