TC9148P

The TC9148P is C-MOS LSI developed for use on the infrared remote control transmitter.This LSI has 18 functions, and total 75 commands can be transmitted:63 commands by the continuous keys of multiple keying is possible and 12 commands by the single shot keys.In no event shall Sensitron Semiconductor be liable for any damages that may result from an accident or any other cause during operation of the user's units according to the datasheet(s). Sensitron Semiconductor assumes no responsibility for any intellectual property claims or any other problems that may result from applications of information, products or circuits described in the datasheets.

Features of the TC9148P are:(1)wide  range of operating supply voltage allows low voltage operation  (VDD=2.2 ~ 5.0V); (2)C-MOS structure assures extremely low power dissipation; (3)multiple keying is possible (max. sextet); (4)less external parts; (5)adaptable to other models as code bits are available; (6)an oscillator can be constructed only by connecting an LC or ceramic resonater as the oscillation circuit is housed.

The absolute maximum ratings of the TC9148P can be summarized as:(1)supply voltage:6.0 V;(2)input voltage:Vss-0.3 to Vdd+0.3V;(3)storage temperature:-55 to 125;(4)operating temperature:-20 to 75;(5)power dissipation:200mW;(6)output voltage:Vss-0.3 to Vdd+0.3V;(7)Txout output current:-5mA.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
