The Education of MassiveProng (Pt 3 of 275) (001/634) (364/634)
inverter 5516 output pulls down the inverter 5518 output node so that
transistor 5520 advantageously pulls the signal INT all the way to 5V.
Conversely, a low-to-high transition by inverter 5516 pulls the input
of inverter 5518 low via "open collector" inverter FET 5522, whereupon
inverter 5518 output starts to go high, turning on the feedback
transistor 5524 and accelerating the low-to-high transition at
inverter 5518 output with greatly reduced power dissipation. The OC
inverters 5522 and 5528 are sized sufficiently large relative to FETs
.
