The PT2241-16S is a remote control encoder IC manufactured by Princeton Technology Corp. This encoder is utilized in various wireless remote control applications.

Applications:

• Remote-controlled toys
• Car alarms
• Garage door openers
• Wireless security systems
• Industrial remote controls

Features:

• CMOS Technology
• Low power consumption
• Multiple address options
• Up to 8 data pins
• External oscillator control
• Available in DIP and SOP packages

Benefits:

• Long Battery Life: Low power consumption enables extended use in battery-operated devices.
• Enhanced Security: Address lines provide multiple address options, reducing the possibility of code duplication and unauthorized control.
• Flexible Control: The 8 data pins enable control of multiple functions.
• Simple Oscillator Adjustment: External oscillator components allow easy frequency adjustment.

Additional Details:

The PT2241-16S transmits address and data code when the transmit enable pin is activated. The address and data are determined by the logic levels applied to the corresponding pins. It works in conjunction with compatible decoder ICs to create a complete remote control system. The operating voltage typically ranges from 2.4V to 12V. The '16S' designation identifies a specific configuration of address and data pins within the PT2241 series. An external resistor connected between OSC1 and OSC2 is used to set the oscillator frequency.
