HCPL2631VM

Logic Output Optoisolators Overview

The HCPL2631VM is a high-speed, dual-channel logic output optocoupler manufactured by onsemi. It integrates an 850 nm AlGaAs LED with a high-speed integrated photodetector logic gate. The device supports data rates up to 10 Mbps and features open-collector outputs capable of wired-OR configuration. Key electrical parameters include a propagation delay of 75 ns (typical), rise/fall times of 50 ns/12 ns, and a minimum common-mode transient immunity of 5 kV/µs. It operates within a supply voltage range of 4.5 V to 5.5 V and withstands an isolation voltage of 2500 Vrms. The component is housed in an 8-SMD package and functions reliably across a temperature range of -40°C to 100°C.

• Computer peripheral interface circuits
• Logic gate level signal transmission between isolated domains

Logic Output Optoisolators Procurement Notes

Verify the specific suffix VM indicates the surface-mount 8-SMD packaging variant distinct from through-hole DIP versions. Confirm the manufacturer designation as onsemi, noting historical brand transitions from Broadcom. Ensure compliance with RoHS standards and check for lead-free certification if required by assembly specifications. Validate the operating temperature range extension to 100°C against specific application thermal constraints.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high data throughput is required. The open-collector output architecture allows for direct interfacing with various logic families without additional pull-up components in wired-OR setups. Consider the 8-SMD form factor for space-constrained printed circuit board layouts. Evaluate the 5 kV/µs CMTI rating against the noise environment of the target system to ensure signal integrity.

Logic Output Optoisolators Part Context

This device belongs to the HCPL2631M series, which includes single and dual-channel variants such as the HCPL2601M and HCPL2611M. These components share a common design philosophy of combining high-speed LEDs with integrated logic gates. The series is designed to replace older discrete optocoupler solutions by offering higher bandwidth and better noise immunity in a compact package format suitable for modern electronic systems.
