Lifecycle

Current status not flagged as discontinued per last available information availability may vary by region and date

Close equivalents and alternatives within the same family

- HCPL-070A-500E tape and reel packaging version same electrical performance different packing

- HCPL-070A general ordering code family member verify packing and compliance suffix

- HCPL-0701-000E similar family device with different CTR bin and characteristics verify fit in your design

Functionally similar alternatives different gain speed or package

- HCPL-2701 SOIC 8 phototransistor output lower gain higher speed verify performance tradeoffs

- 4N32 and 4N33 Darlington optocouplers DIP packages not the same footprint but often used as functional substitutes in through hole designs

Exact cross references depend on CTR bin speed isolation rating and package If you need a drop in or closest match contact our sales team via the Y-IC website for a curated list and availability

Key Application Areas

Logic level isolation between microcontrollers and higher voltage domains

Industrial control inputs PLC and sensor interface with strong noise immunity

Power supply feedback and status monitoring while maintaining isolation

Relay driver interface and general signal buffering where high gain is needed

Ground loop elimination in measurement and data acquisition systems

Motor control and inverter auxiliary circuits not for high speed gate drive but suitable for status and control signals
