TLP2631
TLP2631 TOSHIBA photocoupler GaAℓAs IRed & Photo IC TLP2631 Isolated Line Receiver Simplex / Multiplex Data Transmission Computer-Peripheral Interface Microprocessor System Iinterface Digital Isolation for A / D, D / A Conversion Unit: mm The TOSHIBA TLP2631 dual photocoupler consists of a pair of GaAℓAs light emitting diode and integrated high gain, high speed photodetector. This unit is 8-lead DIP. The output of the detector circuit is an open collector, Schottky clamped transistor. A Faraday shield integrated on the photodetector chip reduces the effects of capacitive coupling between the input LED emitter and the high gain stages of the detector. This provides an effective common mode transient immunity of 1000 V/μs. • Input current threshold: IF = 5 mA (max) • Switching speed: 10MBd (typ.) • Common mode transient immunity: ±1000 V/μs (min) • Guaranteed performance over temperature: 0 to 70°C • Isolation voltage: 2500 Vrms (min) • UL recognized: UL1577, file no.
