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

• 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

PT2264
A group of Code Bits is called a Code Word. A Code Word consists of 12 AD bits followed by one Sync
Bit. The 12 AD bits are determined by the corresponding states of A0 ~ A7 and A8/D3 ~ A11/D0 pins at
the time of transmission. When Data Type of PT2264 is used, the address bits will decrease
accordingly.
For example: In the 4 Datas Type where the address has eight (8) bits, the transmitting format is:
8 Address Bits 4 Data Bits Sync. Bit
PT2264 / PT2294 have a maximum of twelve (12) Address Bits, four (4) Address/Data bits. The
following diagram shows the code bits with their corresponding pins.

0 Data A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 Sync Bit
1 Data A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 D0 Sync Bit
2 Data A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 D1 D0 Sync Bit
3 Data A0 A1 A2 A3 A4 A5 A6 A7 A8 D2 D1 D0 Sync Bit
4 Data A0 A1 A2 A3 A4 A5 A6 A7 D3 D2 D1 D0 Sync Bit
The Code Bits A0 ~ A7 and A8/D3 ~ A11/D0 are determined by the states of A0 ~ A7 and A8/D3 ~
A11/D0 pins. For example, when the A0 (Pin No. 1) is set to “1” (VCC), the Code Bit A0 is synthesized
as “1” bit. In the same manner, when it (A0 Pin) is set to “0” (VSS) or left floating, the Code Bit A0 is
synthesized as a “0” or “f” bit respectively.
