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.
