HCPL-4100

To prevent damage and/or degradation induced by ESD when handling and assembling the HCPL-4100 component, it is advised to take normal static precautions .

The purpose of the HCPL-4100 optocoupler is to operate as a transmitter in equipment using the 20 mA current loop. It is designed to provide optical coupling of the signal from the logic input to the 20 mA current loop, breaking ground loops and providing high immunity to common mode interference. The HCPL-4100 is compatible with LSTTL, TTL, and CMOS logic, and guarantees performance over a temperature range of 0°C to 70°C. It also features internal shielding for high common mode rejection and has guaranteed on and off output current levels. The optocoupler is UL recognized for 2500 V rms for 1 minute and CSA approved. The HCPL-4100 is part of a system that includes the HCPL-4200 receiver for isolated 20 mA current loop transmission in various applications such as computer peripherals, industrial control equipment, and data communications equipment.
