Descriptions
The IRM-2638TF4 is 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. IRM-2638TF4 is the standard IR remote control
receiver series, supporting all major transmission codes.
