Description

The TSOP48..UH1 – 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 de-

coded by a microprocessor. TSOP48..UH1 is the

standard IR remote control receiver series, supporting

all major transmission codes.
