12级二进制串行计数/分频器CD4040B


Description
CD4020B,CD4024B,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(D and F suffixes),16-lead dual-in-line plastic packages(K suffix),and in chip form (H suffix).

The CD4024B types are supplied in 14-lead hermetic dual-in-line ceramic packages(D and F suffixes),14-lead dual-in-line plastic packages(E suffix),and in chip form (H suffix).
