CD4040BMS: CMOS Ripple-Carry Binary Counter/Dividers

CD4020BMS - 14 Stage
CD4024BMS - 7 Stage
CD4040BMS - 12 Stage

CD4020BMS, CD4024BMS, and CD4040BMS are ripplecarry 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 CD4020BMS, CD4024BMS and the CD4040BMS is supplied in these 14 lead outline packages:

CD4020B CD4024B CD4040B
Braze Seal DIP H4W H4Q H4X
