TSOP322..
Vishay Semiconductors
IR Receiver Modules for Remote Control Systems
Description
The TSOP322.. - 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. TSOP322.. is the stan-
dard IR remote control receiver series for 3 V supply
1
voltage, supporting all major transmission codes.
