TSOP17.. TELEFUNKEN Semiconductors Rev. A2, 24-Sep-96 1 (6) Photo Modules for PCM Remote Control Systems Available types for different carrier frequencies Type f0 Type f0 TSOP1730 30 kHz TSOP1733 33 kHz TSOP1736 36 kHz TSOP1737 36.7 kHz TSOP1738 38 kHz TSOP1740 40 kHz TSOP1756 56 kHz Description The TSOP17.. – series are miniaturized receivers for in- frared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses. 94 8691 GND VS OUT Features Photo detector and preamplifier in one package Output active low Internal filter for PCM frequency High immunity against ambient light Improved shielding against electric field disturbance 5 Volt supply voltage, low power consumption TTL and CMOS compatibility Continuous transmission possible (tpi/T0.4) Block Diagram 94 8136 PIN Input AGC Control Circuit Band Pass Demodu- lator 100 k 1 2 3 VS OUT GND
