16797

Taping available for topview and sideview assembly Lead (Pb)-free component Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC

MECHANICAL DATA
Pinning: 1 = GND, 2 = N.C., 3 = VS, 4 = OUT

DESCRIPTION
The TSOP352.., TSOP354.. series are miniaturized SMD IR receiver modules for infrared 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 TSOP352.. is compatible with all common IR remote control data formats. The TSOP354.. is optimized to suppress almost all spurious pulses from energy saving lamps but will also suppress some data signals. This component has not been qualified according to automotive specifications.
