WebNov 21, 2012 · TTL with Active Pullup n With a high output, VCC=5V n QS is cutoff RB RC n QP is forward active n With a low output, QP VOUT n QS is saturated VA QI QS n QP should be cutoff VB QO The low output case is unsatisfactory VC RD with this circuit: VBP = VEP = VBEP = The “Totem Pole Output” solves this problem. A digital use of a push–pull configuration is the output of TTL and related families. The upper transistor is functioning as an active pull-up, in linear mode, while the lower transistor works digitally. For this reason they are not capable of sourcing as much current as they can sink (typically 20 times less). Because of the way these circuits are drawn schematically, with two transistors stacked v…
