LR series

      The LR series is designed as reciver module.It is ideal for the wireless transfer of serial data, control, or command information in the favorable 260-470MHz band.Typical applications include remote control, keyless entry, garage / gate openers, lighting control, medical monitoring / call systems, remote industrial monitoring, periodic data transfer, home / industrial automation, fire / security alarms, remote status / position sensing, long-range RFID and wire elimination.
      LR series has many features.The first one is it would have long range.The second one is it would have low cost.The third one is it would have PLL-synthesized architecture.The fourth one is it would have direct serial interface.The fifth one is its data rates to 10,000bps.The sixth one is t it would have qualified data output.The seventh one is no external components needed.The seventh one is it would have low power consumption.The eighth one is it would have wide supply range (2.7 to 5.2VDC).The ninth one is it would have compact surface-mount package.The tenth one is it would have wide temperature range.The next one is it would have RSSI and Power-down functions.The last one is it would have no production tuning.That are all the features.
      Some absolute maximum ratings of LR series have been concluded into several point as follow.The first one is about its supply voltage which would be from -0.3 to +3.6 Vdc.The second one is about its supply voltage, using resistor which would be from -0.3 to +5.2 Vdc.The third one is about its any input or output pin which would be from -0.3 to +3.6 Vdc.The fourth one is about its RF input which would be 0 dBm.The fifth one is about its operating temperature which would be -40 to +70 °C.The sixth one is about its storage temperature which would be from -45 to +85 °C.Tha last one is about its soldering temperature which would be +225°C for 10 seconds.
      Notes about LR series.Exceeding any of the limits of this section may lead to permanent damage to the device. Furthermore, extended operation at these maximum ratings may reduce the life of this device.
