TC9285P

The TC9285P is an infrared Remote Control signal receiving LSI is suited for remote control of audio system,TV, VTR, CD player, etc.In combination with the transmission LSI:TC9243P,TC9243F, a remote control system can be easily composed.On the TC9285P, the lower 4 bits of a system code permitting receiving of remote control signal can be set and the upper 4 bits have been fixed at"100000". (Settable range:"80"-"83" HEX).Once a system code permitting receiving has been set up, only when the system code for the received remote control signal is in accord with the set system code, the following key data code is accepted.

Features of the TC9285P are:(1)basic functions:11 functions, hold pulse:9 functions,cyclic pulse:2 functions; (2)3 functions out of 7 hold pulse functions are shift key outputs and can be output in parallel with other outputs corresponding to double-pushed signals sent from sending side; (3)1 function out of 2 cyclic pulse functions can be control outputs using an external key in addition to control by remote control signal; (4)8bit system codes are detected. System codes permitting signal receiving can be set up to 4 bits.Interference with other equipment can be thus prevented.

The absolute maximum ratings of the TC9285P can be summarized as:(1)supply voltage:-0.3 to 6.0 V;(2)input voltage:GND-0.3 to Vdd+0.3V;(3)storage temperature:-65 to 150;(4)operating temperature:-40 to 85;(5)power dissipation:350mW.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
