6N137-L
High CMR, High Speed TTL Compatible Optocouplers
Description
The 6N137-L consists of a high efficient
AlGaAs Light Emitting Diode and a high
speed optical detector. This design provides
excellent AC and DC isolation between the
input and output sides of the Optocoupler.
The output of the optical detector features an
open collector Schottky clamped transistor.
The enable function allows the optical
detector to be strobed. The internal shield
ensures high common mode transient
immunity. A guaranteed common mode
transient immunity is up to 15,000V/μs.
The Optocoupler operational parameters are
guaranteed over the temperature range from
-40oC ~ +85oC.

Notes
1. A 0.1µF or bigger bypass capacitor for VCC is needed as shown in Fig.1
2. Peaking driving circuit may be used to speed up the LED. The peak drive current of LED may go up to 50mA
and maximum pulse width 50ns, as long as average current doesn’t exceed 20mA.
3. tPLH (propagation delay) is measured from the 3.75 mA point on the falling edge of the input pulse to the 1.5 V
point on the rising edge of the output pulse.
4. tPHL (propagation delay) is measured from the 3.75 mA point on the rising edge of the input pulse to the 1.5 V
point on the falling edge of the output pulse.
5. The tELH enable propagation delay is measured from the 1.5 V point on the falling edge of the enable input
pulse to the 1.5 V point on the rising edge of the output pulse.
6. The tEHL enable propagation delay is measured from the 1.5 V point on the rising edge of the enable input
pulse to the 1.5 V point on the falling edge of the output pulse.
7. CMH is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in
a high logic state (i.e., VO > 2.0 V).
8. CML is the maximum tolerable rate of fall of the common mode voltage to assure that the output will remain in
a low logic state (i.e., VO < 0.8 V).
9. No external pull up is required for a high logic state on the enable input. If the enable pin is not used, tying it to
VCC.
10. Device is considered a two-terminal device: pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7, and 8
shorted together.
11. In accordance with UL1577, each optocoupler is proof tested by applying an insulation test voltage 3000 V
rms for one second (leakage current less than 5 uA). This test is performed before the 100% production test for
partial discharge
12. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage 6000 V
rms for one second (leakage current less than 5 uA). This test is performed before the 100% production test for
partial discharge
