12-stage binary counter
HEF4040B
MSI
DESCRIPTION
The HEF4040B is a 12-stage binary ripple counter with a
clock input (CP), an overriding asynchronous master reset
input (MR) and twelve fully buffered outputs (O
0
to O
11
).
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 CP. Each counter stage is a
static toggle flip-flop. Schmitt-trigger action in the clock
input makes the circuit highly tolerant to slower clock rise
and fall times.
