ELM611(TA)

Logic Output Optoisolators Overview

The ELM611(TA) is a single-channel logic output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode optically coupled to a high-speed integrated photo-detector logic gate with a strobable output. The device provides a data rate of 10Mbps and supports a maximum DC forward current of 50mA. It offers a minimum isolation voltage of 3750Vrms and a common-mode transient immunity of 20kV/µs. Propagation delays are limited to 100ns, with typical rise and fall times of 40ns and 10ns respectively. The component 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 ordering suffix when sourcing this component, as variations such as the '-V' designation may indicate different packaging formats like tape and reel. Confirm that the requested part matches the standard ELM611(TA) specifications regarding the 5-SOP package and logic gate output type. Ensure compliance with RoHS standards and check for any regional distribution restrictions before placing orders. Cross-reference manufacturer datasheets to confirm active status and availability constraints.

Logic Output Optoisolators Selection Notes

Select the ELM611(TA) for designs requiring fast digital isolation with a strobable output feature. This component is suitable for replacing pulse transformers in high-frequency applications. Consider the 5-SOP footprint for space-constrained PCB layouts. Verify that the system's voltage requirements align with the 3750Vrms isolation capability. Ensure the operating temperature range meets the environmental conditions of the target application.

Logic Output Optoisolators Part Context

The ELM611(TA) belongs to the ELM6xx series of high-speed logic gate photocouplers from Everlight Electronics.
