The gate output is sufficient to drive four 74LS inputs. Note the unusual arrangement of the power supply pins for these ICs! Each output Q0-Q9 goes high in turn as counting advances. The reset input should be low 0V for normal operation counting

Decade counter with decoded 7-segment display outputs and display enable. Mikroelektronik in der Amateurpraxis [ Microelectronics for the practical amateur ] in German 3 ed.
Octal bus transceiver ; tri-state outputs. The series facilitates simpler circuit design through relatively low power consumption, a wide range of supply voltagesseriex vastly increased load-driving capability fanout.
Buffered models can accommodate higher electrical currents, but have a greater risk of introducing unwanted feedback. Octal D-type flip-flop ; positive-edge trigger tri-state. DIP 14, SO The series was extended in the late s and s with new models that were given 45xx and 45xxx designations, but are usually still regarded by seriee as part of the series.
