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.

Latch-Up Avoidance

Unlike conventional CMOS devices, CMOS

devices are immune to latch-up.

V2

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.

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.

Switching Frequency

The SP4251 has a maximum 25 kHz switching rate.
