HCPL-263N

HCPL-263N Description

The HCPL-263N from Broadcom Limited is a high-performance, dual-channel logic output optoisolator designed for robust signal isolation in demanding industrial and electronic applications. Featuring a 3750Vrms isolation voltage, this device ensures reliable galvanic isolation between input and output circuits, making it ideal for noise-sensitive environments. With a 10MBd data rate and Schottky-clamped open-collector outputs, it delivers fast switching performance (rise/fall times of 42ns/12ns) while maintaining low propagation delays (100ns max). Its DC input type and 4.5V–5.5V supply voltage compatibility simplify integration into digital systems.

HCPL-263N Features

• Dual-Channel Isolation: Two independent channels (2/0 input/output configuration) for bidirectional or redundant signal isolation.
• High Noise Immunity: 15kV/µs common-mode transient immunity (CMTI) ensures stable operation in electrically noisy environments.
• Fast Switching: Optimized for high-speed data transmission (10MBd) with Schottky-clamped outputs for reduced signal distortion.
• Robust Construction: MSL 1 (Unlimited) moisture sensitivity and through-hole mounting enhance durability in harsh conditions.
• Low Power Consumption: 1.3V typical forward voltage (Vf) and 10mA max forward current (If) minimize energy usage.
• Wide Compatibility: 50mA output current per channel supports interfacing with TTL, CMOS, and other logic families.

HCPL-263N Applications

• Industrial Automation: Isolate PLCs, motor drives, and sensors to prevent ground loops and noise interference.
• Medical Equipment: Ensure patient safety in diagnostic devices by isolating high-voltage and low-voltage circuits.
• Telecommunications: Protect signal integrity in high-speed data lines and network infrastructure.
• Power Electronics: Interface control logic with power switches (e.g., IGBTs, MOSFETs) in inverters and converters.
• Test & Measurement: Isolate ADC/DAC signals to reduce cross-talk in precision instrumentation.
