ICPL2530, ICPL2531
HIGH SPEED DUAL CHANNEL
OPTICALLY COUPLED ISOLATOR
PHOTOTRANSISTOR OUTPUT
APPROVALS
l
UL recognised, File No. E91231
DESCRIPTION
These dual channel diode-transistor optocouplers
use a light emitting diode and an integrated photon
detector to provide 2500Volts
RMS
electrical isolation
between input and output. Seperate connection for
the photodiode bias and output transistor collector
improve the speed up to a hundred times that of a
conventional photo-transistor coupler by reducing
the base-collector capacitance.

CURRENT TRANSFER RATIO is defined as the ratio of output collector current,I
O
, to the forward LED
input current, I
F
times 100%.
Device considered a two-terminal device: pins 1,2,3, and 4 shorted together and pins 5,6,7 and 8 shorted
together.
Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
Common mode transient immunity in Logic High level is the maximum tolerable (positive) dVcm/dt on
the leading edge of the common mode pulse V
CM
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, V
CM
to assure that the output
will remain in Logic Low state (i.e. V
O
< 0.8V).
The 1.9k
Ω
load represents 1 TTL unit load of 1.6mA and the 5.6k
Ω
pull-up resistor.
The 4.1k
Ω
load represents 1 LSTTL unit load of 0.36mA and the 6.1k
Ω
pull-up resistor.
The frequency at which the a.c. output voltage is 3dB below the low frequency asymptote.
