ACPL-2670L

Overview

The ACPL-2670L is a commercial grade, two-channel high-speed optocoupler manufactured by Broadcom Limited. It features a hermetically sealed ceramic DIP-16 package with gold-plated leads. The device supports a data rate of 10 Mb/s and provides 1500 VDC isolation voltage. Key electrical parameters include a typical current transfer ratio of 100%, a forward current of 20 mA, and a forward voltage of 1.5 V. Rise and fall times are typically 90 ns and 40 ns, respectively. The component operates within a temperature range of -55°C to +100°C and dissipates up to 200 mW.

Feature Summary

• Hermetically sealed construction in a 16-pin ceramic DIP package for environmental stability
• High-speed signal transmission capability at 10 Mb/s data rates
• Robust electrical isolation with 1500 VDC rating and 1 kV/µs common-mode transient immunity

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal interfacing between microprocessors and power circuits

Procurement Notes

Verify the specific suffix (e.g., -300) against the required packaging or lead configuration, as standard part numbers may vary. Confirm RoHS compliance status, as some variants may not meet current environmental standards. Ensure the supplier provides valid datasheets matching the exact part number to avoid receiving incompatible logic output types. Check for availability constraints due to potential long production cycles.

Selection Notes

Select this component when high-speed digital isolation is required in harsh environments. The hermetic seal makes it suitable for applications where moisture or gas ingress could compromise standard plastic packages. Consider the 10 Mb/s speed limit for bus interfaces. Verify that the open-collector Schottky clamped output aligns with the destination circuit's input requirements.

Part Context

This device belongs to the ACPL-2 series of high-speed optocouplers from Broadcom. It is designed for commercial-grade applications requiring reliable signal transmission across isolated barriers. The family includes variants with different output configurations and packaging options, but the ACPL-2670L specifically offers dual channels in a robust ceramic DIP format.

Replacement Considerations

Direct substitutes include other hermetically sealed dual-channel optocouplers with similar 10 Mb/s speeds and 1500 VDC isolation. Verify pinout compatibility and output logic type before substitution.
