The HCPL-4100 from AVAGO is a high-reliability, 1-channel optocoupler designed to provide electrical isolation in a variety of industrial and electronic systems. Housed in a standard DIP-8 package, this device features a robust isolation voltage of 3750 Vrms, effectively protecting sensitive control circuits from high-voltage transients and ground loop noise. Its open-collector output and inverter logic gate type make it suitable for interfacing between logic circuits with different voltage levels. With a maximum propagation delay of 1.6 µs and a baud rate of up to 20 KBps, it is well-suited for digital signal isolation in moderate-speed communication interfaces, process control systems, and power supply feedback loops, operating reliably within a 0°C to +70°C temperature range.

Features

• High Isolation Voltage: 3750 Vrms rating ensures reliable signal integrity and protection for low-voltage components in high-noise environments.
• Open Collector Output: Provides flexibility for interfacing with various logic families and allows for wired-OR configurations in bus-oriented systems.
• Moderate Speed Performance: Maximum propagation delay of 1.6 µs supports digital signal transmission at baud rates up to 20 KBps.
• Robust Drive Capability: Maximum continuous output current of 30 mA enables direct driving of relays, LEDs, or other low-power loads.
