IEEE 1284 Parallel Data Bus Protection

Problem: Overcurrent fault conditions.

A misconnection of the connectors or a foreign metal object placed into the connector can cause a large overcurrent event, which could damage internal electronics.

 

Solution: PolySwitch devices.

PolySwitch devices help limit the flow of dangerously high currents during fault conditions and reset back to normal operating mode once the fault condition is removed.

Problem: Transient Surge Voltages and Electrostatic Discharge (ESD)

Electrostatic discharge (ESD) events can occur during installation and also any time the user disconnects the source from the receiver. This can severely damage the equipment.

 

Solution: PESD devices

Extremely low capacitance ESD protection devices, such as Raychem PESD devices, help shunt ESD away from sensitive circuitry in electronic devices without inducing signal distortion.
