74OL6001 Equivalent & Substitute Parts

Part Overview

The 74OL6001 is a Logic Output Optoisolator manufactured by onsemi, featuring 5.3kV isolation voltage, push-pull totem pole output configuration, and 15MBd data rate capability. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The 6-DIP through-hole package and specific electrical characteristics define the substitution parameters for this optoisolator category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74OL6001 is determined by the following critical parameters:

• Isolation Voltage: Minimum 5300Vrms required for equivalent isolation performance
• Output Configuration: Push-pull or totem pole output topology for direct signal drive capability
• Data Rate: Minimum 15MBd to maintain signal integrity in high-speed applications
• Common Mode Transient Immunity: Minimum 5kV/µs for noise immunity in switching environments
• Package Compatibility: 6-DIP or 8-DIP through-hole packages for PCB integration
• Supply Voltage Range: Compatibility with 4.5V to 5.5V logic supply rails
• Output Current: Minimum 40 mA per channel for adequate load driving capability

The HCPL-2200 is identified as a substitute part; however, it exhibits reduced isolation voltage (3750Vrms versus 5300Vrms), lower CMTI (1kV/µs versus 5kV/µs), reduced data rate (2.5MBd versus 15MBd), and different output topology (tri-state versus push-pull). These differences require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 74OL6001 is obsolete; active production has ceased. The HCPL-2200 maintains active product status with current manufacturing availability. Both components share REACH unaffected and EAR99 export classification status.

Selection between these components depends on application-specific isolation voltage, CMTI, and data rate requirements. The 74OL6001 provides superior isolation voltage (5300Vrms), higher CMTI (5kV/µs), and faster data rate (15MBd) performance. The HCPL-2200 offers extended operating temperature range (-40°C to 85°C) and wider supply voltage compatibility (4.5V to 20V), with active product support and availability.

Package differences (6-DIP versus 8-DIP) and output topology variations (push-pull versus tri-state) require PCB layout and circuit design considerations during substitution evaluation.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-2200 directly replace the 74OL6001 in existing designs?

A: Direct replacement requires verification of isolation voltage, CMTI, and data rate requirements. The HCPL-2200 provides lower isolation voltage (3750Vrms versus 5300Vrms), reduced CMTI (1kV/µs versus 5kV/µs), and slower data rate (2.5MBd versus 15MBd). Applications requiring the full 5300Vrms isolation or 15MBd performance cannot use the HCPL-2200 as a direct substitute.

Q: What are the package compatibility considerations?

A: The 74OL6001 uses 6-DIP packaging while the HCPL-2200 uses 8-DIP packaging. Both are through-hole mount types with 0.300" (7.62mm) row spacing. PCB footprint modifications are required for substitution.

Q: How do output topologies differ between these components?

A: The 74OL6001 features push-pull totem pole output, providing active high and low drive capability. The HCPL-2200 uses tri-state output, which includes a high-impedance state. Circuit designs relying on push-pull drive characteristics require redesign for tri-state operation.

Q: What supply voltage considerations apply?

A: The 74OL6001 operates within 4.5V to 5.5V supply range. The HCPL-2200 accepts 4.5V to 20V supply voltage. Designs using higher supply voltages can leverage the HCPL-2200's extended range; however, 5V nominal operation is compatible with both components.

Q: Are there regulatory or compliance differences?

A: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99). No regulatory barriers exist for substitution from a compliance perspective.
