Remote Control System can be constructed together with the PT2248 remote control encoder. The PT2249A Series are packaged in 16 pins DIP (PT2249A version is also available in SOP package) and are capable of controlling 10 functions while the PT2250A Series are packaged in 24 pins DIP and are capable of controlling 18 functions. Several options, inverting/non-inverting IR signal input and/or dependent/independent cyclic (toggle) outputs, are provided to fit different application needs. Features CMOS Technology Low Power Consumption Very High Noise Immunity Able to output parallel multiple keying signals sent from the transmitter (PT2249A is able to output up to 5 functions simultaneously while PT2250A is able to output up to 6 functions simultaneously) Outputs for single pulse, hold pulse and cyclic pulse are provided A single terminal type oscillator by means of RC is provided Code Detection Circuit prevents interference from various types of machines and apparatus Digital Filtering and Code Checking prevent interference from light sources such as PL Lamp without sacrificing the receiving sensitivity Applications Audio Equipment Remote Control Television (TV) Remote Control Video Cassette Recorder (VCR) Remote Control PT2249A/50A v2.4 Page 1 Updated August 2001 Tel : 886-2-29162151 Fax: 886-2-29174598 URL: http://www.princeton.com.tw Remote Control Receiver IC Pin Configurations VSS RXIN HP1 HP2 HP3 HP4 HP5 SP5 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC OSC CODE2 CODE3 SP1 SP2 SP3 SP4 PT2249A & PT2250A Series VSS RXIN HP1 HP2 HP3 HP4 HP5 CP2 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC OSC CODE2 CODE3 SP1 SP2 SP3 CP1 PT2249A (16 PDIP 300 mil) PT2249A-SN (16 SOP 150 mil) (16 PDIP 300 mil) PT2249AI / PT2249AIN PT2249AL / PT2249ALN PT2249AH / PT2249AHN VSS RXIN HP1 HP2 HP3 HP4 HP5 HP6 CP2 CP1 SP10 SP9 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 VCC OSC CODE1 CODE2 SP1 SP2 SP3 SP4 SP5 SP6 SP7 SP8 (24 PDIP 600 mil) PT2250A /PT2250AN PT2250AL / PT2250ALN ANI LH- Advanced Version Inversed RXIN Input Independent Cyclic (Toggle) Outputs Advanced Dependent Cyclic (Toggle) Outputs) Output Format same as "L", except that when HP1 or HP2 is active, it will clear CP1.
