HCPL-4200-300ME

Logic Output Optoisolators Overview

The HCPL-4200-300ME is a logic output optoisolator designed for use as a receiver in 20 mA current loop systems. It features an 8-SMD, Gull Wing surface mount package with a wide operating temperature range of -40°C to 85°C and a supply voltage range of 4.5V to 20V. The device supports a data rate of 20 K Baud at line lengths up to 1400 metres. It provides high common mode rejection and ensures guaranteed on and off thresholds across the specified temperature range.

Logic Output Optoisolators Feature Summary

• Designed specifically for operation as a receiver in equipment utilizing 20 mA current loop protocols
• Provides high common mode rejection capabilities to ensure signal integrity in noisy environments
• Features guaranteed on and off thresholds for reliable digital logic interfacing

Logic Output Optoisolators Applications

• Data acquisition systems using 20 mA current loop transmission
• Process control instrumentation interfaces

Logic Output Optoisolators Procurement Notes

Verify that the specific suffix '300ME' corresponds to the required 8-SMD Gull Wing surface mount package variant rather than the standard DIP configuration. Confirm that the operating temperature range of -40°C to 85°C meets your environmental specifications. Ensure compatibility with LSTTL, TTL, or CMOS logic families for the output interface. Check RoHS compliance status if required by your manufacturing standards.

Logic Output Optoisolators Selection Notes

Select this component when a surface mount solution is required for 20 mA current loop receivers. It is suitable for applications needing isolation between low-voltage logic circuits and higher voltage loop lines. Consider the 20 K Baud data rate limit for signal speed requirements. Verify that the 4.5V to 20V supply range aligns with your system power design constraints.

Logic Output Optoisolators Part Context

This part belongs to the Broadcom HCPL-4200 series of optically coupled current loop receivers. It serves as the receiving end counterpart to transmitters like the HCPL-4100 series. The device facilitates isolated communication in industrial environments where noise immunity and electrical safety are critical. It replaces older through-hole variants with a compact surface mount footprint.

Logic Output Optoisolators Replacement Considerations

Direct replacements include other HCPL-4200 variants such as HCPL-4200-000E or HCPL-4200-500E, provided the package type matches the board layout. Verify pinout compatibility before substituting different package styles.
