ND5100
Receiver IC for infrared remote control systems.
Features
• Supply Voltage Range: 2.7V ~ 6 V
• TTL and CMOS compatibility
• No external components Except PIN Diode
• Available for Carrier Frequencies between 32.7kHz to 56.7kHz,
( Adjusted by zener-Diode Fusing, or using frequency selection PADs. (Refer to frequency selection table & bonding option.) )
• Internal filter for PCM frequency
• Open collector output (built-in Pull-up resistor 42?)
• Output active low
• Enhanced Immunity against all kinds of disturbance light and power noise
• No occurrence of disturbance pulses at output pin within nominal conditions.
• Short settling time after power On ( below 1msec)
