ELM611(TA)-V

Logic Output Optoisolators Overview

The ELM611(TA)-V is a high-speed logic gate photocopler manufactured by Everlight Electronics. It integrates an infrared emitting diode with a high-speed integrated photo detector featuring a strobable output. The device provides 3750 Vrms isolation voltage and supports data transmission rates up to 10 Mbps. Key electrical parameters include a maximum propagation delay of 100 ns, a common-mode transient immunity of 20 kV/µs, and a forward current of 50 mA. It operates within a temperature range of -40°C to +85°C and is housed in a 5-SOP surface-mount package.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '-V' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limit. Ensure design compatibility with the 5-SOP footprint and pinout. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate isolation voltage requirements against system safety standards.

Logic Output Optoisolators Selection Notes

Select this component for applications requiring fast digital signal isolation with logic-level outputs. The strobable output feature allows for precise timing control in data transmission lines. Consider the 10 Mbps speed limit when designing high-frequency circuits. The open collector output requires appropriate pull-up resistor selection. Evaluate thermal management needs given the 50 mA forward current rating.

Logic Output Optoisolators Part Context

The ELM611(TA)-V belongs to the ELM6xx series of high-speed optocouplers from Everlight Electronics. This series is designed for applications demanding rapid signal transfer across isolation barriers. The device utilizes an AlGaAS LED coupled to a high-speed photodetector. It is part of a family including variants like ELM600 and ELM601, sharing similar architectural principles but differing in specific output configurations and performance metrics.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other 10 Mbps logic output optocouplers with comparable isolation ratings. Verify pinout compatibility and electrical characteristics such as propagation delay and CMTI. Cross-reference with manufacturers offering equivalent SOP-5 packages. Ensure replacement parts meet the same UL and VDE approval standards if certification is required.
