The TOSHIBA TLP2530 and TLP2531 dual photocouplers consist of a
pair of GaAAs light emitting diode and integrated photodetector.
This unit is 8-lead DIP.
Separate connection for the photodiode bias and output transistor
collectors improve the speed up to a hundred times that of a
conventional phototransistor coupler by reducing the base-collector
capacitance.

(Note 8) Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
(Note 9) Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm / dt
on the leading egde of the common mode pulse, Vcm, to assure that the output will remain in a
logic high state(i.e., V
O
> 2.0V).
Common mode transient immunity in logic low Level is the maximum tolerable (negative) dVcm / dt
on the trailing edge of the common mode pulse signal, Vcm, to assure that the output will remain in
logic low state(i.e., V
O
> 0.8V).
(Note 10) The frequency at which the ac output voltage is 3dB below the low frequency asymptote.
