Output type: Darlington transistor

Input type: DC LED

CTR (min/max): 600% / 8000% (as provided)

Output current per channel: up to 60 mA

Max output voltage: 18 V

LED forward voltage (typ): 1.25 V

Max DC forward current (If): 5 mA

Turn-on/turn-off (typ): 3 s / 34 s (units as provided; see datasheet for exact timing units)

Mounting: Surface mount (SMD)

Package: 8-SOIC (0.154 in, 3.90 mm width)

Operating temperature: 0°C to 70°C

RoHS: RoHS3 compliant

Base product number: HCPL-073

Inventory reference: Quantity available 1580 (subject to change)

Lifecycle

Current lifecycle status: Broadcom/Avago HCPL series remains widely used; this specific code is generally considered active in many channels. Availability can vary by region and date.

Nearing discontinuation: No formal notice indicated here. Please verify latest status.

Equivalent/alternative models: Formal drop-in equivalents and bin variants are not listed here. For confirmed alternates (including Broadcom ACPL/HCPL family options and cross-vendor matches), contact our sales team via the Y-IC website. We will recommend substitutes matching isolation rating, CTR range, package, and pinout.

If your design needs second-source options or long-term supply planning, our team can provide a detailed cross-reference and lifecycle risk assessment on request.

Key Application Areas

Industrial I/O isolation and PLC signal interfaces
