Description

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:
