Description
The 6N134 consists of a pair of inverting optically coupled gates, each with a light emitting diode and a
unique high gain integrated photon detector in a hermetically sealed ceramic package. The output of the
detector is an open collector Schottky clamped transistor.
This unique dual coupler design provides maximum DC and AC circuit isolation between each input and
output while achieving TTL circuit compatability. The isolator operational parameters are guaranteed from -
55°C to +125°C, such that a minimum input current of 10mA in each channel will sink a six gate fanout
(10mA) at the output with 4.5 to 5.5V Vcc applied to the detector. This isolation and coupling is achieved
with a typical propagation delay of 60ns. Surface Mount Option Available.

Notes
1. Each channel.
2. Measured between pins 1 through 4 shorted together and pins 9 through 16 shorted together.
3. Measured between pins 1 and 2 or 5 and 6 shorted together, and pins 9 through 16 shorted together.
4. Measured between pins 1 and 2 shorted together, and pins 5 and 6 shorted together.
5. The tPLH propagation delay is measured from the 6.5mA point on the trailing edge of the input pulse to
the 1.5V point on the trailing edge of the output pulse.
6. The tPHL propagation delay is measured from the 6.5mA point on the leading edge of the input pulse to
the 1.5V point on the leading edge of the output pulse.
7. CMh is the maximum tolerable common mode transient to assure that the output will remain in a high
logic state (ie. Vo > 2.0V)
8. CMl is the maximum tolerable common mode transient to assure that the output will remain in a low logic
state (ie. Vo < 0.8V)
9. It is essential that a bypass capacitor (0.01 to 0.1µF, ceramic) be connected from pin 10 to pin 15. Total
lead length between both ends of the capacitor and the isolator pins should not exceed 20mm.
10. This is a momentary withstand test, not an operation condition.
