Description: CD4020B, CD4024B, and CD4040B are ripple-carry binary counters. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transistion of each input pulse; a high level on the RESET line resets the counter to its all zeros state. Schmitt trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered.

The CD4020B and CD4040B types are supplied
in 16-lead hermetic dual-in-line ceramic
packages (F3A suffix), 16-lead dual-in-line
plastic packages (E suffix), 16-lead
small-outline packages (NSR suffix), and
16-lead thin shrink small-outline packages (PW
and PWR suffixes). The CD4040B type also is
supplied in 16-lead small-outline packages (M
and M96 suffixes).
The CD4024B types are supplied in 14-lead
hermetic dual-in-line ceramic packages (F3A
suffix), 14-lead dual-in-line plastic packages (E
suffix), 14-lead small-outline packages (M, MT,
M96, and NSR suffixes), and 14-lead thin shrink
small-outline packages (PW and PWR suffixes).
