KH2 series

      The KH2 series is designed as receiver / decoder.It is ideally suited for volume use in OEM applications such as remote control / command and keyless entry.Typical applications include remote control / command, keyless entry, garage / gate openers, lighting control, call systems, home / industrial automation, fire / security alarms, remote status monitoring and wire elimination.
      KH2 series has many features.The first one is that it would have low cost.The second one is that it would have long range.The third one is it would have on-board decoder.The fourth one is that it would have 8 parallel binary outputs.The fifth one is it would have 310 addresses for security and uniqueness.The sixth one is it would have ultra-low power consumption.The seventh one is it would have compact SMD package.The eighth one is it would have advanced synthesized architecture.The ninth one is it would have received data output.The tenth one is it would have transmission validation.The next one is it would have no production tuning.The next one is it would have no external RF components required (except an antenna).The last one is pin-compatible with original KH.That are all the features.
      Some absolute maximum ratings of KH2 series have been concluded into several points 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 -30 to +70 °C.The sixth one is about its storage temperature which would be from -45 to +85 °C.The seventh one is about its soldering temperature which would be +225°C for 10 seconds.
      Notes about KH2 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.
