HCPL-6650

Logic Output Optoisolators Overview

The HCPL-6650 is a commercial-grade, four-channel high-speed optocoupler manufactured by Broadcom Limited. It features hermetically sealed ceramic Flat-Pack 16 packaging with gold-plated leads. The device supports a data rate of 10 MBd and provides an isolation voltage of 1500 Vdc. Each channel utilizes a GaAsP infrared LED coupled to an open-collector Schottky-clamped transistor output. Key electrical parameters include a typical forward voltage of 1.5 V, maximum forward current of 20 mA, and continuous output current of 25 mA. The unit operates within a temperature range of -55°C to +125°C.

Logic Output Optoisolators Feature Summary

• Hermetically sealed ceramic flat-pack construction for environmental stability
• Internal shielding provides 1000V/µs common-mode transient immunity
• Schottky-clamped outputs ensure fast switching performance
• TTL-compatible logic interface for direct digital integration

Logic Output Optoisolators Applications

• Military and aerospace systems requiring MIL-PRF-38534 compliance
• Medical equipment demanding high isolation reliability
• Industrial control systems with noisy environments

Logic Output Optoisolators Procurement Notes

Verify the specific package variant (SMD/SMT) against design requirements, as the HCPL-6650 series includes surface-mount options distinct from through-hole versions. Confirm RoHS status and lead finish specifications directly with the manufacturer or authorized distributors. Ensure supply chain sources are authorized to guarantee authenticity for hermetically sealed components used in critical applications.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust environmental sealing. The 1500 Vdc isolation rating suits standard industrial interfaces, while the 10 MBd speed supports moderate baud rates. Consider the HCPL-5650 if higher 2500 Vdc isolation is necessary. Verify that the open-collector output configuration aligns with the receiving circuit's pull-up requirements.

Logic Output Optoisolators Part Context

Part of the HCPL series, the HCPL-6650 represents a legacy high-performance optocoupler line originally developed by Avago Technologies. It shares internal chip characteristics with other variants in the family, differing primarily in packaging and pinout configurations. The device remains relevant for applications requiring proven reliability and military-grade sealing standards.

Logic Output Optoisolators Replacement Considerations

For higher isolation voltage requirements, consider the HCPL-5650 series which offers 2500 Vdc isolation. Direct pin-to-pin replacements may vary; verify electrical compatibility and package dimensions before substitution.
