Remote Control Encoder IC
PT2264
DESCRIPTION
PT2264 is a remote control encoder paired with PT2294 utilizing CMOS Technology.
It encodes data and address pins into a serial coded waveform suitable for RF modulation.
PT2264 has a maximum of 12 bits of tri-state address pins providing up to 531,441 (or 312) address codes; thereby, drastically reducing any code collision and unauthorized code scanning possibilities.
FEATURES
• • • • • • • • • CMOS Technology Low Power Consumption Very High Noise Immunity Up to 12 Tri-State Code Address Pins Up to 4 Data Pins Wide Range of Operating Voltage: VCC = 8 ~ 15 V Single Resistor Oscillator Latch or Momentary Output Type Available in DIP and SO Package
APPLICATIONS
• • • • Remote Control Fan Home Security/Automation System Remote Control Toys Remote Control for Door Bell
