HCPL-M453

Description

Introduction to HCPL-M453: HCPL- M453 is a high-performance Darlington- npn-output optocoupler from Broadcom Limited. Key features include:
High Common Mode Rejection Ratio (CMRR) for robust signal transmission.
Fast speed, suitable for high-frequency applications.
Small outline 5-lead package, saving board space. HCPL- M453 finds application in various fields such as line receivers with high immunity to noise, logic ground isolation for TTL/CMOS systems, and replacing phototransistors or pulse transformers for improved efficiency.

Features

The HCPL-M453 optocoupler features a high common mode rejection (CMR), fast speed, and a compact 5-pin outline package. It also has improved linearity compared to phototransistor types and offers a UL Recognized isolation level of 3750 Vrms. These features make it suitable for applications such as line receivers with high CMR and low input-output capacitance, logic ground isolation for various digital protocols, and board space-saving replacements for slower phototransistors or pulse transformers.

Package

The HCPL-M453 optocoupler has a small outline 5-lead package.

Pinout

The HCPL-M453 optocoupler has a pin count of
Here are the functions for each pin:

• 
  
• Pin 1 (Input):
• It's connected to the input circuit, where it receives signals from the primary side.
• 
  
• Pin 2 (Output):
• This output pin provides a high-impedance signal at the secondary side, isolated from the input.
• 
  
• Pin 4 (VCC or Power Supply)):
• Connects to the power supply for both sides of the optocoupler.
• 
  
• Pin 5 (Ground or Signal Ground)):
• Provides a common ground connection for all signals within the circuit.

Ensure proper connections and isolation ratings when using the HCPL-M453 optocoupler.
