Analog Signal Isolation
The TOSHIBA TLP751 consists of GaAAs high-output light
emitting diode and a high speed detector of one chip photo diode-
transistor. This unit is 8-lead DIP.
TLP751 has internal base connection. This base pin should be used for
analog application or enable operation. If base pin is open, output signal
will be noisy by environmental condition. For this case, TLP750 is
suitable.
