The TOSHIBA TLP558 consisits of a GaAℓAs light emitting diode and
integrated high gain, high speed photodetector.
This unit is 8−lead DIP package.
The detector has a three state output stage that provides source drive
and sink drive, and built−in schmitt trigger. The detector IC has an
internal shield that provides a guaranteed common mode transient
immunity of 1000V / µs. TLP558 is inverter logic type. For buffer logic
type, TLP555 is in line−up.
