Package and Ordering Notes
The listed package is 8-pin DIP with 8 pins, leads, lands or contacts. The featured image is a generic package illustration for form-factor identification and is not an actual date-code or lot photograph. Lifecycle is recorded as Obsolete; confirm current factory support and last-time-buy constraints before design-in.
Sourcing Guidance
CNY74-2H is obsolete or discontinued. Source only with date-code, label, package and traceability checks, and validate the suggested replacement independently.
For an accurate quotation, include the full MPN, target quantity, acceptable date-code range, packaging format and destination. Icearth can help review traceability documents, label photos and electrical/package alignment before order placement.
Manufacturer Documentation
Technical values were checked against Vishay documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
CNY74-2H selection and design context
CNY74-2H is cataloged as a Optocoupler in the CNY74 family. Its recorded function is dual-channel phototransistor-output optocoupler in an industry-standard DIP package. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Channels: 2 isolated channels. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Current Transfer Ratio: 50% to 600%. Check steady-state, transient and thermal margin in the intended operating mode.
- Isolation Test Voltage: 5300 V RMS. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Collector-Emitter Voltage: 70 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
Application and qualification considerations
When evaluating this component, confirm the ratings that control system compatibility, including supply conditions, interface or signal limits, timing, thermal behavior and package constraints. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for CNY74-2H
The recorded package is 8-pin DIP, the temperature range is -55°C to +100°C, and the lifecycle status is Obsolete as of 2026-07-19. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
