RF1 Vishay Semiconductors IR Receiver Modules for Remote Control Systems Description The TSOP348.
.
RF1 - 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.
TSOP348.
.
RF1 is the standard IR remote control receiver series for 3 V supply voltage, supporting all major transmission codes.
