IW4020B

Description

The IW4020B is ripple-carry binary counter.All counter stages are master-slave flip-flops.The state of a

counteradvances one count on the negative transition of each input pulse,a high level on the R ESE T line

resets thecounter to its all zeros state.Schmitt trigger action on the input-pulse line permits unlimited rise and

fall times
