NJL31H/31V/32H/33H/34H000A
INFRARED REMOTE CONTROL RECEIVER
GENERAL DESCRIPTION
The NJL30H/V000A series are small and high performance receiving devices for infrared remote control system.
They can operate under low and wide supply voltage (2.7V to 5.5V) with enhanced immunity against power saving light.
The NJL30H/V000A series have ten kinds of package including seven types of metal case to meet the various applications.
FEATURES
1. Wide and low supply voltage 2.7V to 5.5V
2. Low supply current
0.43mA typ.
Vcc=3.3V
3. Mold type and metal case type to meet the design of front panel.
4. Line-up for various center carrier frequencies.
APPLICATIONS
1. Home application such as Room light Air-conditioner, etc
.
2. AV instruments such as Audio, TV, DVD, STB etc.
