1 / 8 page Document Number: 81732 www.vishay.com Rev. 1.2, 20-Aug-08 121 IR Receiver Modules for Remote Control Systems New TSOP348.., TSOP344.. Vishay Semiconductors MECHANICAL DATA Pinning: 1 = OUT, 2 = GND, 3 = VS FEATURES • Very low supply current • Photo detector and preamplifier in one package • Internal filter for PCM frequency • Improved shielding against EMI • Supply voltage: 2.5 V to 5.5 V • Improved immunity against ambient light • Insensitive to supply voltage ripple and noise • Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC DESCRIPTION The TSOP348.., TSOP344.. series are miniaturized receivers for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame, the epoxy package acts as an IR filter. The demodulated output signal can be directly decoded by a microprocessor. The TSOP348.. is compatible with all common IR remote control data formats. The TSOP344.. is optimized to suppress almost all spurious pulses from energy saving fluorescent lamps but will also suppress some data signals. This component has not been qualified according to automotive specifications.
