Optoisolators - Logic Output have a variety of applications from logic and circuit isolation to data transmission and signal safety. HCPL2631S is one example of an optoisolator with a logic output that features high common-mode transient immunity, low propagation delay time, and an enhanced isolation of 1500 Vrms. It can be used in a variety of applications such as automotive systems, industrial automation and control, appliances, and medical instruments.

The HCPL2631S contains an infrared emitting diode (LED) and a photo IC coupled together in a single 7-pin package. The package features an LED that is optically coupled to a combination of NPN and PNP photodetectors and an output stage with a totem-pole arrangement. This allows the HCPL2631S to provide an isolated voltage output with logic high/low level output.

The LED of the HCPL2631S is triggered by supplying a current of 1 mA to the anode of the LED. When this happens, the LED emits light which is received and detected by the detector IC in the HCPL2631S. This detector then triggers the output stage of the optoisolator, producing a logic high (VIH) voltage level.

The logic low output voltage (VIL) is produced by discharging the LED current. This is done by applying a voltage (Vcc) across the LED and resetting the logic input. There is a delay between the logic input and output as a result of the signal\'s propagation time through the HCPL2631S optoisolator.

The HCPL2631S is specifically designed for current-loop applications such as that used for high speed, analog-to-digital converter transduction systems. It is also suitable for isolation of control logic gates or for status/control signalling between data processing stations. The HCPL2631S can further be used for adding additional isolation levels in data transmission systems.

The HCPL2631S optoisolator can also be used to eliminate the problem of ground loops. This optoisolator uses light instead of wires to connect the input and output circuits. This isolation feature helps to eliminate noise that is often caused by the electric current that flows in the common ground output of the power supply. This helps to reduce degradation of the signal signals and improves the signal integrity.

Lastly, the HCPL2631S is extremely durable and reliable, withstanding harsh environmental conditions such as high humidity, temperature, and vibration. It is also highly resistant to electromagnetic interference (EMI) due to its good isolation characteristics. This makes the HCPL2631S suitable for applications in rugged and hostile environments.
