The 4020BPC is a 14-stage ripple carry binary counter. The counters are advanced one count
on the negative transition of each clock pulse. The
counters are reset to the zero state by a logical “1” at the
reset input independent of clock.
Wide supply voltage range: 3.0V to 15V
High noise immunity: 0.45 VDD (typ.)
Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS
Medium speed operation: 8 MHz typ. at VDD = 10V
Schmitt trigger clock input
16 pin DIP. Manufactured by Fairchild.
