Product Overview

The HCPL-M452-000E is a single-channel high-speed optocoupler from Broadcom, featuring a SO-5 surface-mount package (JEDEC MO-155 standard). Designed for high-frequency signal transmission and electrical isolation, it offers 1 Mb/s data rate and high common-mode rejection, effectively separating low-voltage control circuits from high-voltage systems. Ideal for industrial automation, data communications, and switching power supplies, the device supports TTL-compatible logic levels and open-collector outputs, with safety approvals including UL1577 (3750Vrms isolation) and CSA certification.

Key Features

• Ultra-Compact Surface-Mount Design:
  The SO-5 miniature package occupies only 25% of traditional DIP space, compatible with infrared vapor phase reflow and wave soldering for dense PCB layouts.
• High-Speed Signal Transmission:
  Supports 1 Mb/s data rate with 0.8µs typical propagation delay, suitable for high-frequency TTL/CMOS logic communications.
• Superior Common-Mode Rejection:
  Achieves 15,000 V/µs CMR (similar to HCPL-M453), suppressing electromagnetic interference in industrial environments to maintain signal integrity.
• Broad Electrical Compatibility:
  TTL-compatible input current (16mA) and -0.5V to 30V output voltage range with open-collector outputs, adapting to diverse logic interfaces.
• Global Safety Approvals:
  Certified by UL1577 (3750Vrms), CSA, and RoHS lead-free standards, ensuring compliance with medical and industrial safety requirements.

Technical Specifications

Typical Applications

• Industrial Automation:
  Provides electrical isolation between PLCs and sensors, eliminating ground loops via high CMR to ensure stable control signal transmission.
• High-Speed Data Communications:
  Used in RS-485/CAN bus interfaces for high-speed data isolation, converting TTL to TTL/CMOS levels while protecting against surge currents.
• Switching Power Supplies:
  Enables PWM signal isolation and feedback control via open-collector outputs, optimizing power efficiency and reducing high-frequency noise.
• Computer Peripherals:
  Isolates host systems from peripherals (e.g., printers) with 1 Mb/s data transfer, safeguarding against electrostatic interference.
• Medical Electronics:
  Meets 3750Vrms isolation requirements for medical devices, separa
