SGM4568
8-Bit Bidirectional Voltage-Level
Translator with Auto Direction Sensing
GENERAL DESCRIPTION
FEATURES
The SGM4568 is an 8-bit, non-inverting, bidirectional
● Power Supply Voltage Range (VCCA ≤ VCCB)
voltage-level translator which features two independent
A Ports: 1.2V to 5.5V
configurable power-supply lines. The A and B ports
B Ports: 1.65V to 5.5V
● Support VCCA or VCCB Isolation
track the VCCA supply and VCCB supply respectively. The
When VCCA or VCCB is Low, Device Enters
supply voltage range is 1.2V to 5.5V for A ports and
Power-Down Mode
1.65V to 5.5V for B ports. The device provides a
bidirectional translation function between the different
● OE Input Circuit Referenced to VCCA
voltage nodes (including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V
● Support Partial-Power-Down Function
and 5V).
● Support Push-Pull Output
The SGM4568 has an output enable (OE) function,
● Low Power Consumption
which controls the outputs states. When OE goes low,
● -40℃ to +85℃ Operating Temperature Range
all outputs enter into the high-impedance state. The OE
● Available in Green TSSOP-20 and TQFN-3×3-20L
should be connected to GND via a pull-down resistor,
Packages
and the minimum resistor value is depended on the
current source capability of the driver.
APPLICATIONS
The SGM4568 features the OE input circuit which is
Universal Asynchronous Receiver/Transmitter
referenced to VCCA.
General Purpose I/O (GPIO)
The SGM4568 is available in Green TSSOP-20 and
Smart Phones
TQFN-3×3-20L packages. It operates over an ambient
Portable Equipment
temperature range of -40℃ to +85℃.

you have additional comments or questions, please contact your SGMICRO representative directly.
OVERSTRESS 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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.

ESD SENSITIVITY CAUTION
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.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete 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.
