H11L2S(TA)

Logic Output Optoisolators Overview

The H11L2S(TA) is a logic output optocoupler manufactured by Everlight Electronics Co Ltd. It features a single channel with an open collector output type and operates within a voltage range of 3V to 16V. The device provides 5000Vrms isolation voltage and supports a data rate of 1MHz. Key electrical parameters include a maximum DC forward current of 60mA, a typical forward voltage of 1.15V, and a maximum continuous output current of 50mA. Propagation delays are specified at 4µs for both low-to-high and high-to-low transitions, with rise and fall times of 100ns. It functions in temperatures from -55°C to +100°C and utilizes a 6-SMD gull wing package.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation during procurement, as variations such as (TA) or (V) may indicate different packaging formats like cut tape or reel. Confirm moisture sensitivity level requirements and storage conditions prior to assembly. Ensure the selected variant matches the required surface mount footprint and lead finish specifications for the target PCB design.

Logic Output Optoisolators Selection Notes

Select this component when a fast switching speed is required compared to standard transistor output isolators. The open collector output allows for flexible pull-up voltage selection, accommodating various logic families. Consider the 6-SMD package size constraints and thermal dissipation capabilities within the 250mW power rating limit for the final application design.

Logic Output Optoisolators Part Context

This part belongs to the H11LX series of logic output optocouplers from Everlight. It serves as a surface-mount alternative to through-hole DIP versions like the H11L2. The series is designed for applications demanding reliable digital signal transfer across isolated boundaries while maintaining compact board space utilization.

Logic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements within the same manufacturer family include the H11L1S(TA) and H11L2S(TA)-V. Verify that substitute parts maintain identical propagation delay characteristics and isolation voltage ratings to ensure circuit performance consistency without redesign.
