TSOP344..SB1F
Vishay Semiconductors
IR Receiver Modules for Remote Control Systems
Description
The TSOP344..SB1F - series are miniaturized receiv-
ers 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. TSOP344..SB1F is a
standard IR remote control receiver series for 3 V
supply voltage with excellent suppression of distur-
bance signals.
