1 / 8 page Document Number: 82135 www.vishay.com Rev. 2.4, 28-Oct-08 1 IR Receiver Modules for Remote Control Systems New TSOP41.., TSOP43.. Vishay Semiconductors MECHANICAL DATA Pinning 1 = OUT, 2 = GND, 3 = VS FEATURES • Low supply current • Photo detector and preamplifier in one package • Internal filter for PCM frequency • Improved shielding against EMI • Supply voltage: 2.7 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 TSOP41.., TSOP43.. 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 directly be decoded by a microprocessor. The main benefit of the TSOP41.. is the compatibility to all IR remote control data formats. The TSOP43.. is optimized to better suppress spurious pulses from fluorescent lamps, LCD TVs or plasma displays. This component has not been qualified according to automotive specifications.

The output voltage V O should not be pulled down to a level below 1 V by the external circuit. The capacitive load at the output should be less than 2 nF. |
