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
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 1000V / μs. Unit in mm

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). * t ≤ 1 msec duration. ** 2mm below seating plane.

(Note 1) 2mm below seating plane (Note 2) The VCC supply voltage to each TLP2631 isolator must be bypassed by a 0.01μF capacitor or larger. This can be either a ceramic or solid tantalum capacitor with good high frequency characteristic and should be connected as close as possible to the package VCC and GND pins each device. (Note 3) Device considered a two−terminal device: Pins 1, 2, 3 and 4 shorted together, and pins 5, 6, 7 and 8 shorted together. (Note 4) CMH・the maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in the high state (i.e., VOUT > 2.0V). Measured in volts per microsecond (V / μs). Volts/ microsecond can be translated to sinusoidial voltages:
V / μs = (dVCM) Max. = fCM VCM (p.p.) dt
Example: VCM = 319Vpp when fCM = 1MHz using CML and CMH = 1000V / μs data sheet specified minimum. (Note 5) CML・the maximum tolerable rate of fall of the common mode voltage to ensure the output will remain in the low output state (i.e., VOUT > 0.8V). Measured in volts per microsecond (V / μs). (Note 6) Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
