DESCRIPTION
The
66325
high voltage isolator consists of an 850 nm LED optically coupled to a high gain inverting photon detector. The
isolator provides high CTR and low leakage currents over the specified temperature range of -40ºC to +100ºC.The isolator is
built with hermetic components internally optically coupled and encased in a high temperature outer PPS plastic housing.

NOTES:
1)
The duration can be extended to 10 seconds maximum when flow soldering. Otherwise 5 seconds with soldering iron.
2)
Device considered a two terminal device with all Input pins (Anode and Cathode) shorted together and all Output pins (V
CC
, GND and Output) shorted
together.
3)
CURRENT TRANSFER RATIO is defined as the ratio of output collector current, I
O
, to the forward LED input current, I
F
, times 100%.
4)
CM
H
is the maximum tolerable common mode transient to assure the output will remain in a HIGH logic state (ie. V
O
> 2.0 V).
5)
CM
L
is the maximum tolerable common mode transient to assure the output will remain in a LOW logic state (ie. V
O
< 0.8 V).
6)
In applications where dv/dt may exceed 50,000 V/μS (such as static discharge) a series resistor, R
CC
, should be include to protect the detector IC from
destructively high surge currents. The recommended value is R
CC
= 1V/(0.6 * I
F
) mA.
