ACNW261L-300E

Overview

The ACNW261L-300E is a high-speed optocoupler from Broadcom Limited featuring a single channel with tri-state logic output. It operates at a data rate of 10 MBd and provides an isolation voltage of 5000 Vrms. The device utilizes a Photo IC output type and supports a maximum forward current of 5 mA with a typical forward voltage of 1.5 V. Electrical performance includes rise and fall times of 12 ns, with propagation delays up to 95 ns. It functions within a temperature range of -40°C to +105°C and is housed in an 8-pin PDIP Gull Wing package.

Feature Summary

• Integrates tri-state output capability with a dedicated enable pin for flexible bus interfacing
• Provides high common-mode transient immunity rated at 20 kV/µs for noise resilience
• Features built-in slew-rate control to minimize signal reflections and EMI

Applications

• Industrial communication bus systems requiring galvanic isolation
• High-speed data transmission interfaces in noisy environments
• Isolated gate driver circuits for power electronics

Procurement Notes

Verify the specific suffix code to confirm the packaging configuration, as variations exist between tube and reel formats. Ensure the selected variant matches the required operating temperature range and insulation voltage ratings for the target application. Cross-reference the datasheet revision date to confirm compliance with current regulatory standards such as IEC and UL certifications before finalizing procurement orders.

Selection Notes

Select this component when a tri-state output is necessary for shared bus architectures or multi-drop configurations. The high CMTI rating makes it suitable for applications with significant ground potential differences or fast-switching noise sources. Compare propagation delay specifications against system timing requirements to ensure signal integrity is maintained across the isolation barrier.
