Description

The Si8261ACC-A-IP is an electronic component model in the IC Chips product category. It is a pin-compatible, one-channel, drop-in replacement for popular optocouplers with data rates up to 15 Mbps. This device isolates high-speed digital signals and offers performance, reliability, and flexibility advantages not available with optocoupler solutions. The Si8261ACC-A-IP is based on Silicon Labs proprietary CMOS isolation technology, allowing for low-power and high-speed operation. It is resistant to wear-out effects found in optocouplers that degrade performance with increasing temperature, forward current, and device age. This component offers longer service life and dramatically higher reliability compared to optocouplers. Ordering options include open collector output with and without integrated pull-up resistor and output enable options. Automotive Grade is available for certain part numbers, ensuring robustness and low defectivity required for automotive applications.
