Description
The TSOP17.. 鈥?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. TSOP17.. is the
standard IR remote control receiver series, supporting
all major transmission codes.
