DESCRIPTION

The TSOP372..H, TSOP374..H series are miniaturized

receiver modules for infrared remote control systems. A PIN

diode and a preamplifier are assembled on a PCB, the

epoxy lens cap contains an IR filter.

The TSOP374..H series devices are optimized to suppress

almost all spurious pulses from energy saving lamps like

CFLs. The AGC4 used in the TSOP374..H may suppress

some data signals. The TSOP372..H series are provided

primarily for compatibility with old AGC2 designs. New

designs should prefer the TSOP374..H series containing the

newer AGC4.

These components have not been qualified according to

automotive specifications.
