grounding the /TTL pin) will optimize overall propagation
delay and ±swing symmetry.
.* Application Hints:
*
* Connect pin 4 to ground through 1000MΩ resistor to inhibit
* Hysteresis; to invoke Hysteresis, connect pin 4 to V-.
*
* Connect pin 5 to ground to invoke TTL VOH; pin 5 may left open
* for CMOS VOH.
*
* To facilitate .OP, set itl1=200, itl2=200, set node 27 to 13.8V,
* and node 30 to -12V.
