DESCRIPTION

The AD2C111-L is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay. It is designed to replace

electromechanical relays in general purpose switching applications. The relay consists of IR LED optically coupled to a IC that drives two

rugged source-to-source enhancement type DMOS transistors. The 4 pin DIP package offers the combination of reduced package size,

with 5kV input to output isolation. This device also includes over-current circuitry that protects the device from high load currents and

transient spikes by limiting the amount of current that can pass through its output.

APPLICATIONS

• Reed relay replacement

• Meter reading systems

• Medical equipment

• Battery monitoring

• Multiplexers

FEATURES

• Small 4 pin DIP package outline - reduces board space

• Current Limiting - protects device from overcurrents

• High input-output isolation (5kV)

• Low input control power consumption (2.5mA TYP)

• 120mA maximum continuous load current

• 40 ohms maximum on-resistance

• Long life/high reliability
