14-stage binary counter
DESCRIPTION
The HEF4020B is a 14-stage binary ripple counter with a
clock input (CP), an overriding asynchronous master reset
input (MR) and twelve fully buffered outputs (O0, O3 to
O13). The counter advances on the HIGH to LOW
transition of CP. A HIGH on MR clears all counter stages
and forces all outputs LOW, independent of the state of
CP. Each counter stage is a static toggle flip-flop. A feature
of the HEF4020B is: high speed (typ. 35 MHz at
VDD = 15 V).
