PS8821-2-A

Overview

The PS8821-2-A is a high-speed optocoupler from CEL featuring a dual-channel configuration. It integrates a GaAlAs LED input side with a PIN photodiode and high-speed amplifier output stage, providing analog output type isolation. The device operates at a data rate of 1 Mbps and offers an insulation voltage of 2500 Vrms. It is housed in an 8-pin SSOP package. The component supports a maximum operating temperature of +100°C and a minimum operating temperature of -55°C.

Feature Summary

Dual-channel optical coupling for simultaneous signal isolation
High-speed response capability suitable for digital interfaces
Integrated PIN photodiode and amplifier for analog output generation

Applications

High-speed logic interface circuits
Industrial automation control systems
Measurement equipment signal isolation

Procurement Notes

Verify the specific suffix designation against current manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm availability status as distribution channels may list obsolete or limited stock variants. Ensure the selected package matches the required PCB footprint specifications for the 8-pin SSOP form factor.

Selection Notes

Select this component when dual-channel isolation is required within a single package to save board space. The analog output type necessitates specific biasing considerations compared to standard transistor outputs. Verify that the 1 Mbps data rate meets the system timing requirements and that the 2500 Vrms isolation rating satisfies the safety standards for the intended application environment.

Part Context
