DESCRIPTION
The Ei8LC series of monolithic transient voltage
suppressors are designed for applications where
voltage transients, caused by electrostatic
discharge (ESD) and other induced voltage
surges, can permanently damage voltage
sensitive components. These TVS diodes are
characterized by their high surge capability,
extremely fast response time and low on-
resistance.
The Ei8LC series consists of bi-directional diode
arrays with low input capacitances and is
specifically designed to protect multiple or single
data lines with each channel being electrically
independent for multiple I/O port protection.
These monolithic diode array networks can be
used to protect combinations of 8 unidirectional
or bi-directional lines. They provide ESD and
surge protection for sensitive power and I/O
ports. The 8LC series TVS diode array will meet
the surge and ESD per IEC 1000-4-2.
Applications
ESD & surge protection for power lines & I/O
ports
