CD4040BMS中文资料Intersil数据手册PDF规格书

描述 Description

CD4020BMS, CD4024BMS, and CD4040BMS 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.
