SAA3027

The SAA3027 is intended for a generatl purpose infrared remote control system.The device can generate 2048 different commands and utilizes a keyboard with a single-pole switch per key.The commands are arranged so that 32 systems can be addressed,each system containing 64 different commands.

Features of the SAA3027 are:(1)transmitter for 32 * 64 commands;(2)one transmitter controls 32 systems;(3)very low current consumption;(4)for infrared transmission link;(5)transmission by biphase technique;(6)short transmission times:speed-up of system rection time;(7)LC oscillator;no crystal required;(8)input protection;(9)test mode facility.

The quick reference data of the SAA3027 can be summarized as:(1):the parameter is supply voltage range,the symbol is VDD,the rating is 4.75 to 12.6,the unit is V;(2):the parameter is input voltage range,the symbol is VI,the rating is -0.5 to VDD+0.5,the unit is V;(3):the parameter is input current,the symbol is ±II,the rating is max.10,the unit is mA;(4):the parameter is output voltage range,the symbol is VO,the rating is -0.5 to VDD+0.5,the unit is V;(5):the parameter is output current,the symbol is ±IO,the rating is max.10,the unit is mA;(6):the parameter is operating ambient temperature range,the symbol is Tamb,the rating is -25 to +85,the unit is .
