SGM4548/49/50
Dual-Channel, High Speed,
Level Shifters and Drivers
GENERAL DESCRIPTION
FEATURES
The SGM4548/49/50 devices are matched dual-
channel level shifters and drivers. The unique circuit
design provides excellent performance for delivering
2A peak current to highly capacitive loads.
● Wide Power Supply Voltage Range
● Improved Response Times
● Matched Rise Time and Fall Time
● Independent Enable Control for Each Channel
● Reduced Clock Skew between Dual Channels
● Improved Clocking Rate
To reduce problems with time and clock skew,
SGM4548/49/50 are good options, with matching
delays and maintaining integrity of input to output
pulse-widths. Matching rise/fall delay times also improve
the drive capability and speed. Non-overlapping drive
technology is used to minimize the dynamic switching
loss.
● Low Supply Current and Output Impedance
● Output is at Low under UVLO Protection,
ENx Pin Floating or Disable Status
● High Noise Immunity
● -40℃ to +125℃ Operating Temperature Range
● Available in Green SOIC-8 and TDFN-2×2-8L
Packages
The SGM4548/49/50 are available in Green SOIC-8
and TDFN-2×2-8L packages. They operate over an
ambient temperature range of -40℃ to +125℃.
APPLICATIONS
CCD Drivers
Level Shifters and Drivers

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
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.

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.
