14 Stage Ripple Carry Binary Counter IC - CD4020
The CD4020 IC is a ripple-carry binary counter. 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's trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered.
The CD4x Series CD4020 type is 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).
