74OL6010300

Overview

The onsemi 74OL6010300 is a single-channel logic output optoisolator from the OPTOLOGIC series. It features an open collector, Schottky-clamped output capable of sourcing 40 mA per channel. The device supports data rates up to 15 MBd with maximum propagation delays of 180 ns (tpLH) and 120 ns (tpHL). Typical rise and fall times are 50 ns and 5 ns, respectively. It provides 5300 Vrms isolation voltage and a minimum common-mode transient immunity of 5 kV/µs. Operating supply voltage ranges from 4.5 V to 15 V within a commercial temperature range of 0°C to 70°C.

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verify availability through authorized distributors or secondary markets, noting that lead times may be extended. Confirm lot dates and authenticity carefully when sourcing non-new inventory. Ensure replacement strategies account for the discontinuation status to maintain long-term supply chain stability.

Selection Notes

Select this part for applications demanding high-speed digital isolation with robust noise immunity. The Schottky-clamped open-collector output suits TTL and CMOS logic families operating between 4.5 V and 15 V. Consider the 6-DIP package for through-hole mounting requirements. Evaluate thermal constraints within the 0°C to 70°C operating range before implementation.

Part Context

The 74OL6010300 belongs to the OPTOLOGIC family, designed for high-performance logic isolation. It utilizes advanced LED and photodetector technology to achieve fast switching speeds while maintaining electrical safety standards. The device integrates protective structures to enhance reliability in electrically noisy industrial environments.

Replacement Considerations

As the 74OL6010300 is obsolete, verify compatible substitutes such as the 74OL6010300-NDR if available. Check datasheets for matching pinouts, isolation voltages, and speed characteristics to ensure functional equivalence without redesigning the host circuit.
