DESCRIPTION
High common mode transient immunity and very high
current ratio together with 5300 V
RMS
insulation are
achieved by coupling and LED with an integrated high gain
photo detector in an eight pin dual-in-line package.
Separate pins for the photo diode and output stage enable
TTL compatible saturation voltages with high speed
operation.
Access to the base terminal allows adjustment to the gain
bandwidth.
The 6N138 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 kΩ pull-up resistor.
The 6N139 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.
Caution:
Due to the small geometries of this device, it should be
handled with Electrostatic Discharge (ESD) precautions. Proper
grounding would prevent damage further and/or degradation which
may be induced by ESD.
APPLICATIONS
• Microprocessor system interface
• PLC, ATE input / output isolation
• EIA RS232 line receiver
• TTL, CMOS voltage level translation
• Multiplexed data transmission
• Digital control power supply
• Ground loop and electrical noise elimination
AGENCY APPROVALS
• UL1577, file no. E52744, double protection
• DIN EN 60747-5-5 available with option 1

Notes
(1)
Common mode transient immunity in logic high level is the maxium 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 V) 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 a logic low state (i.e. V
O
< 0.8 V).
(2)
In applications where dV/dt may exceed 50 000 V/μs (such as state discharge) a series resistor, R
CC
should be included to protect I
C
from
destructively high surge currents. The recommend value is R
