					INFRARED RECEIVER MODULE                                                 MIM-3xx7J2
  Description
      The MIM-3xx7J2 is miniaturized infrared receivers for
      remote control and other applications requiring improved
      ambient light rejection.
      The separate PIN diode and preamplifier IC are assembled
      on a single leadframe.
      The epoxy package contains a special IR filter.
      This module has excellent performance even in disturbed
      ambient light applications and provides protection against
      uncontrolled output pulses.



     Features
  l   Photo detector and preamplifier in one package
  l   Internal filter for PCM frequency
  l   High immunity against ambient light
  l   Improved shielding against electric field disturbance
 l    3.0-Volt supply voltage; low power consumption
  l   TTL and CMOS compatibility

NOTE 1. Distance between emitter & detector specifies maximum distance that output wave form satisfies
          the standard under the conditions below against the standerd transmitter.

                                   shall be arranged to 50mVp-p under the measuring circuit specified in Fig 2.
NOTE 2. (electro-optical charactistics) shall be satisfied after leaving 2 hours in the normal temperature .
NOTE 3. (electro-optical charactistics) shall be satisfied and no conoid deforms
         and destructions of appearance .(excepting deforms of terminals)


Inspection standard
      1.Among electrical characteristics , total number shall be inspected on items blow.
        1-1 front distance between emitter & detector
        1-2 Current consumption
        1-3 H level output voltage
        1-4 L level output voltage
     2.Items except above mentioned are not inspected particularly , but shall fully satisfy


CAUTION ( When use and storage of this device )
  1.Store and use where there is no force causing transformation or change in quality .
  2.Store and use where there is no corrosive gas or sea(salt) breeze .
  3.Store and use where there is no extreme humidity .
  4.Solder the lead-pin within the condition of ratings. After soldering do not add extra force .
  5.Do not wash this device . Wipe the stains of diode side with a soft cloth. You can
    use the solvent , ethylalcohol or methylalcohol or isupropylene only .
  6.To prevent static electricity damage to the Pre-AMP make sure that the human body
       , the soldering iron is connected to ground before using .
    7.Put decoupling device between Vcc and GND for reduse the noise from power supply line .
    8.The performance of remote-control system depends on environments condition and ability
      of periferal parts. Customer should evaluate the performance as total system in those conditions
      after system up with components such as commander , micon and this receiver module .



Others
     1.This device is not design to endure radiative rays and heavily charged particles .
     2.In case where any trouble or questions arise,both parties agress to make full discussion
       covering the said problem .
