TLP555 is, and GaAℓAs infrared light emitting diode, high-gain, high-speed integrated circuit receiving It is 8PIN DIP optocoupler that combines a light chip.
The light-receiving side has a Schmitt circuit and the three-state output circuit, suction (Shea
Link), you can drive in both directions of exhale (source). In addition, the light receiving IC is
Subjected to a shield, now provides high common mode transient immunity of 1000 V / μs
It is. TLP555 is buffer logic type. The inverter logic type
If necessary, there is a TLP558.

Input threshold current: IF = 1.6 mA (maximum)
The power supply voltage: VCC = 4.5 ~ 20 V
