74HC90 (Decade, Divided by twelve AND binary counter- 4-BIT Binary Counter) light ±6-mA Output Drive at 5Introduction : 74HC90 (Decade, Divided by twelve AND binary counter 4 BIT Binary Counter) Each of these monolithic counters contains four master slave flip flops and additional gating to provide a divide by two counter and a three stage binary counter for which thecount cycle length is divide by five for the 74HS90. All of these counters have a gated zero reset and the 74HS90 also has gated set to nine inputs for use inBCD nines complement
