HCPL-2631

Logic Output Optoisolators Overview

The HCPL-2631 is a high-speed optocoupler featuring two independent channels in an 8-pin DIP package. It combines a GaAsP LED with an integrated high-gain photodetector IC providing open collector outputs with Schottky clamping. Key electrical parameters include a data rate of 10 MBd, isolation voltage of 3750 Vrms (standard) or 5000 Vrms (option -020E), and common mode transient immunity of 10 kV/µs. Typical propagation delays are 100 ns, with rise/fall times of 24 ns and 10 ns respectively. The device operates within a temperature range of -40°C to 85°C.

Logic Output Optoisolators Feature Summary

• Integrates a GaAsP light emitting diode with a high gain photo detector for efficient optical coupling.
• Provides logic output compatibility with LVTTL and LVCMOS standards through open collector Schottky clamped transistors.
• Ensures robust circuit isolation via high common mode transient immunity and verified insulation voltage ratings.

Logic Output Optoisolators Applications

• High-speed digital signal isolation in industrial control systems
• Interface circuits between microprocessors and peripheral devices
• Logic gate applications requiring galvanic isolation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix code against official Broadcom documentation to confirm insulation voltage requirements and packaging type. Standard versions offer 3750 Vrms isolation, while the -020E variant supports 5000 Vrms. Confirm whether surface mount or through-hole packaging is required for the target application before ordering.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transmission up to 10 MBd is required alongside strict galvanic isolation. The open collector output necessitates an external pull-up resistor; ensure the chosen resistor value aligns with the desired switching speed and load current specifications for the specific system architecture.
