CD4020BNSR

CMOS波进位二进制计数器DIVIDERS CMOS RIPPLE-CARRY BINARY COUNTER DIVIDERS

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 transition 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.
