HCPL0501V

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL0501V is a single-channel high-speed transistor output optocoupler from the HCPL05XX series, manufactured by Fairchild Semiconductor. It integrates an AlGaAs LED with a high-speed photodetector transistor in an 8-pin SOIC package. The device features a separate bias connection for the photodiode, which significantly reduces base-collector capacitance to achieve speeds several orders of magnitude faster than conventional phototransistor optocouplers. It supports data rates up to 1 Mbit/s and offers open collector output compatibility with TTL, LSTTL, and CMOS logic interfaces.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High-speed operation achieved through separate photodiode biasing that minimizes base-collector capacitance
• Open collector output configuration compatible with standard logic families
• Compact 8-pin small outline package design for optimized mounting density

• Line receivers
• Pulse transformer replacement
• Output interface to CMOS-LSTTL-TTL logic systems
• Wide bandwidth analog coupling

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific manufacturer origin, as this component is produced by multiple entities including Fairchild, Broadcom, and onsemi. Confirm that the suffix 'V' corresponds to the intended packaging or certification variant required for your design. Ensure the selected unit matches the exact datasheet specifications for isolation voltage and operating temperature range before integration.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required between circuits with different ground potentials. It is suitable for replacing pulse transformers in applications demanding fast signal transmission. Consider the open collector output nature for interfacing with downstream logic gates. Verify thermal performance requirements against the guaranteed operating temperature range specified in the official documentation.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL05XX and HCPL04XX family of high-speed optocouplers. Variants within this series include HCPL0500, HCPL053X (dual channel), and HCPL0452/0453. The HCPL05XX series distinguishes itself by bonding out the base of the input transistor for enhanced noise margin, unlike the HCPL04XX devices. These components are widely used in industrial and communication systems requiring reliable electrical isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include HCPL-0501, HCPL0501R1, and HCPL-0501-XXXE variants. Cross-reference datasheets from Broadcom and onsemi to ensure pinout and electrical parameter compatibility. Verify that alternative sources maintain the same 1 Mbit/s speed rating and isolation voltage specifications.
