DESCRIPTION
High common mode transient immunity and very
high current ratio together with 5300 V
RMS
insula-
tion are achieved by coupling an LED with an inte-
grated high gain photon detector in an eight pin
dual-in-line package. Separate pins for the photo-
diode and output stage enable TTL compatible sat-
uration voltages with high speed operation.
Photodarlington operation is achieved by tying the
V
CC
and
V
O
terminals together. Access to the base
terminal allows adjustment to the gain bandwidth.
The SFH6138 is ideal for TTL applications since the
300% minimum current transfer ratio with an LED
current of 1.6 mA enables operation with one unit
load-in and one unit load-out with a 2.2 k
Ω
pull-up
resistor.
The SFH6139 is best suited for low power logic
applications involving CMOS and low power TTL. A
400% current transfer ratio with only 0.5 mA of LED
current is guaranteed from 0
°
C to 70
°
C.

Notes
1. DC current transfer ratio is defined as the ratio of output collector current,
I
O
, to the forward LED input current,
I
F
times 100%.
2. Pin 7 open.
3. Device considered a two-terminal device: pins 1, 2, 3 and 4 shorted together and pins 5, 6, 7, and 8 shorted together.
4. Using a resistor between pin 5 and 7 will decrease gain and delay time.
5. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV cm/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
>2.0 V) common mode transient immunity in logic low level is the
maximum tolerable (negative) dV
cm
/dt on the trailing edge of the common mode pulse signal, V
CM
, to assure that the output will remain in a
logic low state (i.e.
V
O
<0.8 V).
6. In applications where dv/dt may exceed 50,000 V/
µ
s (such as state discharge) a series resistor, R
CC
should be included to protect
I
C
from
destructively high surge currents. The recommended value is
IV
