DescriptionThe TSOP341.. - series are miniaturized receivers forinfrared remote control systems. PIN diode andpreamplifier are assembled on lead frame, the epoxypackage is designed as IR filter.The demodulated output signal can directly bedecoded by a microprocessor. The main benefit is theoperation with short burst transmission codes andhigh data rates at a supply voltage of 3 V.Features• Photo detector and preamplifier in one package• Internal filter for PCM frequency• Improved shielding against electrical fielddisturbance• TTL and CMOS compatibility• Output active low• Supply voltage range: 2.7 V to 5.5 V• High immunity against ambient light
