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.
· Input current threshold: IF = 5mA(max.)
· Switching speed: 10MBd(typ.)
· Common mode transient immunity: ±1000V / µs(min.)
· Guaranteed performance over temperature: 0~70°C
· Isolation voltage: 2500Vrms(min.)
· UL recognized: UL1577, file no. E67349

(Note 2) The VCC supply voltage to each TLP2631 isolator must be bypassed by a 0.01mF 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.

shorted together.
(Note 4) CMH･the maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in
