TLP554 TOSHIBA Photocoupler GaAAs Ired & Photo-IC TLP554 Isolated Line Receiver Simplex/Multiplex Data Transmission Computer-Peripheral Interface Unit: mm Microprocessor System Interfaces Digital Isolation for A/D, D/A Conversion The TOSHIBA TLP554 a photocoupler which combines a GaAAs IRED as the emitter and an integrated high gain, high speed photodetector. 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/ s. Input Current Threshold : IF = 5 mA (max) Switching Speed : 10 MBd (typ. NRZ) Common mode transient immunity : 1000 V/s (min) Guaranteed Performance over Temperature : 0 to 70C Isolation Voltage : 2500 Vrms (min) UL approved : UL1577, File No.E67349 JEDEC c-UL approved :CSA Component Acceptance Service TOSHIBA 11-10C4 No. 5A, File No.E67349 Weight: 0.54 g (typ.)
