The output of the detector is an open collector Schottky clamped transistor. This unique dual isolator design provides maximum DC and AC circuit isolation between each input and output while achieving TTL circuit compatibility. Tre isolator operational parameters are guaranteed from -55C <0 +125C, such that a minimum input current of 10 mA in each channel will sink a six gate fanout (10 mA) at the output with 4.5 to 5.5 V Vec applied to the detector. This isolation aid coupling is achieved with a typical propagation delay of 55 nsec. DIMENSIONS IN-MILLIMETERS ANO (INCHES!
