SGM4578
8-Bit Bidirectional Voltage-Level Translator
for Open-Drain and Push-Pull Applications
GENERAL DESCRIPTION
FEATURES
The SGM4578 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 1.65V 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
● Support VCCA or VCCB Isolation
When VCCA or VCCB is Low, Device Enters
Power-Down Mode
The SGM4578 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. It is
beneficial for reducing quiescent current consumption.
When VCCA is powered, OE has an internal pull-down
current source.
● No Specific Power Sequences Required for VCCA
and VCCB
● Support Partial-Power-Down Function
● -40℃ to +85℃ Operating Temperature Range
● Available in Green TSSOP-20 and TQFN-3×3-20L
Packages
The SGM4578 is available in the 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 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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
