H11L3VM

Logic Output Optoisolators Overview

The H11L3VM is a logic output optoisolator manufactured by onsemi, featuring an open collector output and a single channel configuration. It provides an isolation voltage of 4170Vrms with a common mode transient immunity (CMTI) rating. The device supports a data rate of 1MHz, with typical propagation delays of 4µs for both low-to-high and high-to-low transitions. Rise and fall times are typically 100ns. It operates within a supply voltage range of 3V to 15V and withstands a maximum DC forward current of 30mA. The component is housed in a 6-DIP package with a pitch of 0.300 inches (7.62mm) and functions across a temperature range of -40°C to +85°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix VM against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match design requirements. Ensure compliance with RoHS3 directives as indicated in official documentation. Cross-reference the 6-DIP package dimensions with PCB footprint libraries to prevent assembly errors. Confirm operating temperature ranges align with the intended environmental conditions of the final application.

Logic Output Optoisolators Selection Notes

Select this component when high CMTI and Schmitt trigger input noise rejection are required for reliable digital signal transmission. The open collector output allows flexibility in pull-up resistor selection for different logic voltage levels. Consider the 1MHz data rate limit for high-speed applications. Verify that the 4170Vrms isolation rating meets safety standards for the specific equipment category being designed.

Logic Output Optoisolators Part Context

The H11L3VM belongs to the H11L3 series of logic output optocouplers from onsemi. This series is designed for general-purpose digital isolation tasks where noise immunity is critical due to the integrated Schmitt trigger. The VM suffix typically denotes specific packaging or compliance attributes within the manufacturer's lineup, distinguishing it from other variants in the same functional family.

Logic Output Optoisolators Replacement Considerations

Check for direct substitutes within the H11L3 series such as H11L3M, ensuring pin compatibility and identical electrical specifications. Verify that any alternative maintains the same 6-DIP package and isolation voltage ratings to ensure mechanical and electrical interchangeability without redesigning the circuit board.
