SGM4574
4-Bit Bidirectional Voltage-Level Translator
for Open-Drain and Push-Pull Applications
GENERAL DESCRIPTION
FEATURES
The SGM4574 is a 4-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 1.65V to 5.5V for A ports and
2.3V to 5.5V for B ports. The device provides a
bidirectional translation function between the different
voltage nodes (including 1.8V, 2.5V, 3.3V and 5V).
● Power Supply Voltage Ranges (VCCA ≤ VCCB
A Ports: 1.65V to 5.5V
)
B Ports: 2.3V to 5.5V
● Direction-Control Signal is Not Required
● Data Rates
Push-Pull: 24Mbps
Open-Drain: 2Mbps
● No Specific Power Sequences Required for VCCA
and VCCB
The SGM4574 has an output enable (OE) function,
which controls the inputs and outputs states. When OE
goes low, all I/Os 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 UTQFN-1.8×1.8-12L,
TQFN-2×2-12L and SOIC-14 Packages
APPLICATIONS
Smart Phones
Portable Devices
Handheld Devices
PC/Tablet
The SGM4574 features the OE input circuit which is
referenced to VCCA
.
The SGM4574 is available in Green UTQFN-1.8×1.8-12L,
TQFN-2×2-12L and SOIC-14 packages. It operates over
an ambient temperature range of -40℃ to +85℃.

OVERSTRESS CAUTION
ESD SENSITIVITY CAUTION
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any otherconditions beyond those indicated in the operational
sectionof thespecification is not implied. Exposureto absolute
maximum rating conditions for extended periods may affect
reliability.
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
circuitdesign, specificationor other related things if necessary
without notice at any time.
