Description
The ESDAxxSC5 and ESDAxxSC6 are monolithic
voltage suppressors designed to protect
components which are connected to data and
transmission lines against ESD.
They clamp the voltage just above the logic level
supply for positive transients, and to a diode drop
below ground for negative transient.
