SGM4568
8-Bit Bidirectional Voltage-Level
Translator with Auto Direction Sensing
GENERAL DESCRIPTION
FEATURES
The SGM4568 is an 8-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 5.5V 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 5.5V
)
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 SGM4568 has an output enable (OE) function,
which controls the outputs states. When OE goes low,
all outputs enter into the high-impedance state. 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 TSSOP-20 and TQFN-3×3-20L
Packages
APPLICATIONS
The SGM4568 features the OE input circuit which is
Universal Asynchronous Receiver/Transmitter
General Purpose I/O (GPIO)
Smart Phones
referenced to VCCA
.
The SGM4568 is available in Green TSSOP-20 and
TQFN-3×3-20L packages. It operates over an ambient
temperature range of -40℃ to +85℃.

OVERSTRESS CAUTION
ESD SENSITIVITY CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. 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 very small parametric changes could cause the
device not to meet its published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
