High Speed Logic Interface and Isolation Using Broadcom HCNW2611-500E Optically Coupled Gate Device
Product Overview
The 6N137, HCPL-26xx/06xx/4661, and HCNW137/26x1 series are optically coupled gates designed for high-speed logic interfacing and isolation. These devices combine a GaAsP light-emitting diode with an integrated high-gain photodetector, featuring an enable input for strobing and an open-collector Schottky-clamped transistor output. They offer robust common-mode transient immunity, up to 15 kV/s, ensuring maximum AC and DC circuit isolation while maintaining TTL compatibility. Guaranteed AC and DC operational parameters across a temperature range of 40 C to +85 C ensure reliable system performance in demanding environments. Applications include isolated line receivers, computer-peripheral interfaces, microprocessor system interfaces, digital isolation for A/D and D/A conversion, switching power supplies, and ground loop elimination.
