Description

The TSOP344..SB1F - series are miniaturized receivers 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.
