Download the TSOP1238 datasheet PDF.
This datasheet also covers the TSO variant, as both devices belong to the same photo modules for pcm remote control systems family and are provided as variant models within a single manufacturer datasheet.
General Description
The TSOP11..
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.

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. The main benefit is the operation with short burst transmission codes (e.g. RECS 80) and high data rates.
