LC72321N

The LC72321N is designed as one kind of 64-key infrared remote control transmitter IC that incorporates all key-scanning, oscillator and timing functions on-chip, resulting in a very low external component count. This device generates 71 function codes using the 64 function keys. The output data format comprises the mask-programmed custom code, the parity field, the mask-programmed system code, the product code, the function code and the data check code.

Features of the LC72321N are:(1)low external component count;(2)64 function keys;(3)71 function codes;(4)mask-programmable custom and system codes;(5)64 product codes;(6)output conforms to Japan's association for electric home appliances recommended standards for infrared remote controls;(7)on-chip input pull-down resistors;(8)2.0 to 3.6 V supply;(9)24-pin MFP.

The absolute maximum ratings of the LC72321N can be summarized as:(1)Maximum supply voltage: VSS-0.3 to 5.5 V;(2)Maximum input voltage:VSS-0.3 to VDD+0.3 V;(3)Maximum output voltage: VSS-0.3 to VDD+0.3 V;(4)Allowable power dissipation: 150 mW;(5)Operating temperature:40 to + 85 °C;(6)Storage temperature:50 to + 125 °C.
