PT4203 Encoder IC DESCRIPTION FEATURES PT4203 is encoder utilizing CMOS Technology specially designed for remote control applications. It 20 has 2 Address. It can support up to 4 Data Bits and is housed in 8 pin SOP package. It encodes address and data codes into a coded waveform suitable for RF modulation. The pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantage. Furthermore, PT4203’s intrinsic feature of being able to support 4 data bits considerably reduces inventory pressures. CMOS technology Low power consumption Least external components High noise immunity Single resistor oscillator Operating voltage: 3.0V~14V 4 Data pins 20 2 address codes Available in SOP package Reduction of inventory pressures APPLICATIONS Burglar alarm system Car security system Car/Garage door controller Home/Office security system Personal alarm system BLOCK DIAGRAM OTP Data/ Address Tel: 886-66296288‧Fax: 886-29174598‧ http://www.princeton.com.tw‧2F, No. 233-1, Baociao Rd., Sindian Dist., New Taipei City 23145, Taiwan PT4203 APPLICATION CIRCUIT 8 PINS POWER FAILURE CIRCUIT Warning: Be careful to use this above application circuit which will cause the VDD pin damaged.
