TSOP22..WE1

Vishay Semiconductors

IR Receiver Modules for Remote Control Systems

Description

The TSOP22..WE1 - series are miniaturized receiv-

ers 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. TSOP22..WE1 is the

standard IR remote control receiver series, support-

ing all major transmission codes.
