TLP751 TOSHIBA Photocoupler GaAℓAs Ired + Photo IC TLP751 Digital Logic Ground Isolation Line Receiver Microprocessor System Interfaces Switching Power Supply Feedback Control Analog Signal Isolation Unit in mm The TOSHIBA TLP751 consists of GaAℓAs 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. • Switching speed: tpHL = 0.3μs (typ.)
