? semiconductor components industries, llc, 2015 march, 2015 ? rev. 8 1 publication order number: mc74ac4040/d mc74ac4040 12-stage binary ripple counter the mc74ac4040 consists of 12 master-slave flip-flops. the output of each flip-flop feeds the next and the frequency at each output is half that of the preceding one. the state of the counter advances on the negative-going edge of the clock input. reset is asynchronous and active-high. state changes of the q outputs do not occur simultaneously because of internal ripple delays. therefore, decoded output signals are subject to decoding spikes and may have to be gated with the clock of the mc74ac4040 for some designs. features ? 140 mhz typ. clock ? outputs source/sink 24 ma ? operating voltage range: 2.0 to 6.0 v ? high noise immunity ? these are pb?free devices 15 16 14 13 12 11 10 2 1 34567 v cc 9 8 q11 q10 q8 q9 reset clk q1 q12 q6 q5 q7 q4 q3 q2 gnd figure 1. pinout: 16?lead packages conductors (top view) function table clock reset output state l no change l advance to next state x h all outputs are low www. onsemi.com ordering information see detailed ordering and shipping information in the package dimensions section on page 5 of this data sheet. soic?16 d suffix case 751b 1 16 marking diagram a = assembly location wl = wafer lot y = year ww = work week g = pb?free package 1 16 ac4040g awlyww
