The PT2262 Remote Control Encoder is the industry-standard IC for wireless communication and security systems. At Electrapac, we recommend this DIP-18 chip for makers building custom wireless remotes, garage door openers, or smart home automation links.

Product Overview

The PT2262 is a CMOS LSI encoder designed for remote control system applications. It encodes data and address pins into a serial code waveform suitable for modulation onto an RF (Radio Frequency) carrier, typically used with 315MHz or 433MHz transmitter modules. It is the perfect companion to the PT2272 decoder IC also available at www.electrapac.com.

Key Features for Electrapac Customers

• Tri-State Addressing: Each of the address pins can be set to "Low," "High," or "Floating." This creates over half a million unique code combinations, ensuring your neighbor’s remote won't trigger your device.

• Low Power Consumption: The PT2262 has an incredibly low standby current, making it ideal for battery-powered key fobs that need to last for years.

• Adjustable Oscillation: By changing a single external resistor ($R_{osc}$), you can match the transmission frequency to your specific receiver's requirements.

• Flexible Data/Address Setup: The 12 pins can be configured as 12 address pins or a combination (e.g., 8 address pins and 4 data pins) depending on your project's complexity.

• Wide Operating Voltage: Works reliably with everything from a 5V regulated supply to a 12V alkaline remote battery.

  Primary Applications

  • Wireless Security Systems: Building DIY home alarms or window/door sensors.

  • Garage Door Openers: Replacing or creating custom remotes for gate and garage motors.

  • Remote Fan/Light Control: Controlling household appliances wirelessly across a room.

  • Industrial Paging: Simple one-way wireless notification systems.

  • Toy Remotes: Designing custom controllers for hobbyist RC cars or boats.

  Why Shop at Electrapac?

  We source the PT2262 with high-quality CMOS wafers to ensure minimal frequency drift and stable transmission even as battery voltage drops. At www.electrapac.com, we provide the communication ICs that let your projects "talk" without the clutter of wires.
