LATCH-UP

In the past, most CMOS IC’s were susceptible to a damaging

phenomena known as latch-up. This occurred when an ESD

current spike or other large signal was applied to any of the

pins of an IC. The LMC7215 and LMC7225 both are de-

signed to make them highly resistant to this type of damage.

They have passed qualification tests with input currents on

any lead up to 300 mA at temperatures up to 125˚C.
