NJL71H/71V/72H/73H/74H000A INFRARED REMOTE CONTROL RECEIVER ■ GENERAL DESCRIPTION The NJL70H/V000A series are small and high performance receiving devices for infrared remote control system. They can operate under low and wide supply voltage (2.4V to 5.4V). Also, their supply current is low comparing to the NJL60H/V000A and NJL80H/V000A. The features, low and wide supply voltage, low supply current are suitable for battery operated items. ■ FEATURES 1. Wide and low supply voltage 2.4V to 5.5V 2. Low supply current 0.6mA max. 3. Mold type and metal case type to meet the design of front panel. 4. Line-up for various center carrier frequencies. ■ APPLICATIONS 1. AV instruments such as Audio, TV, VCR, CD, MD etc. 2. Home application such as Air-conditioner, Fan etc. 3. Battery operated instruments such as Toy, Camera etc. ■ LINE-UP Mold/Metal case View Hight Mold type Top Metal Case type Top Side Carrier 5.4mm 6.3mm 8mm Frequency fo= 36 kHz NJL71H360A NJL71V360A NJL72H360A 36.7 kHz NJL71H367A NJL71V367A NJL72H367A 38 kHz NJL71H380A NJL71V380A NJL72H380A 40 kHz NJL71H400A NJL71V400A NJL72H400A Regarding other frequency or packages, please contact to New JRC individually. 11mm NJL73H360A NJL73H367A NJL73H380A NJL73H400A 15mm NJL74H360A NJL74H367A NJL74H380A NJL74H400A ■ BLOCK DIAGRAM Vcc Head Amp 2nd Amp Comparator 3rd Amp 22K Vout B.P.F.
