Description
This pin supports two interface options:
Single-pin control mode. A nominal 3-
volt supply connection is required.
Complementary-pin control mode. A
complementary CMOS control signal
to V1 is supplied to this pin.
Switch control input, CMOS logic level.

Exceeding absolute maximum ratings may cause
permanent damage. Operation should be
restricted to the limits in the Operating Ranges
table. Operation between operating range
maximum and absolute maximum for extended
periods may reduce reliability.
Latch-Up Avoidance
Unlike conventional CMOS devices, CMOS
devices are immune to latch-up.
Electrostatic Discharge (ESD) Precautions
When handling this CMOS device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the specified rating.
Switching Frequency
The SP4251 has a maximum 25 kHz switching rate.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the SP4251
in the 8-lead MSOP package is MSL1.
