The PT2260-R4S is a remote control encoder IC manufactured by Princeton Technology Corp. It is designed for encoding data for transmission via radio frequency (RF) or infrared (IR) in remote control systems. This IC is commonly paired with decoder ICs from the PT2272 series to create a complete remote control solution.

Applications

• Wireless remote controls for home appliances (TVs, stereos, etc.)
• Remote controlled toys
• Garage door openers
• Car alarm systems
• Security systems (wireless sensors, alarm panels)

Features

• CMOS Technology: Provides low power consumption and high noise immunity.
• Multiple Address Options: Allows for a large number of unique device addresses, minimizing interference between devices.

Additional Details

The PT2260-R4S typically operates with a supply voltage of 5V. The address and data pins can be configured using DIP switches or jumpers to set the device address and data being transmitted. The encoded data is then modulated and transmitted using an RF or IR transmitter. The 'R4S' suffix likely denotes a specific package type or configuration option.
