m54/m74hc192 m54/m74hc193 october 1992 hc193 - synchronous up/down binary counter hc192 - synchronous up/down decade counter b1r (plastic package) order codes : m54hcxxxf1r m74hcx xxm1r m74hcxxxb1r m74hcxxxc1r f1r (ceramic package) m1r (micro package) c1r (chip carrier) pin connections (top view) nc = no internal connection description . high speed f max = 54 mhz (typ.) at v cc =5v . low power dissipation i cc =4 m a (max.) at t a =25 c . high noise immunity v nih =v nil =28%v cc (min.) . output drive capability 10 lsttl loads . symmetrical output impedance |i oh |=i ol = 4 ma (min.) . balanced propagation delays t plh =t phl . wide operating voltage range v cc (opr) = 2 v to 6 v . pin and function compatible with 54/74ls192-193 the m54/74hc192/193 are a high speed cmos syn- chronous up/down decade counters fab- ricated in silicon gate c 2 mos technology. they have the same high speed performance of lsttl combined with true cmos low power consumption. the counter has two separate clock inputs, an up count input and a down count input. all outputs of the flip-flop are simultaneously triggered on the low to high transi- tion of either clock while the other input is held high. the direction of counting is determined by which input is clocked. this counter may be preset by entering the desired data on the data a, data b, data c, and data d input. when the load input is taken low the data is loaded independently of either clock input. this feature allows the counters to be used as divide-by-n counters by modifying the count length with the preset inputs. in addition the counter can also be cleared. this is accomplished by inputting a high on the clear input. all 4 internal stages are set to low independently of either count input. both a borrow and carry output are provided to enable cascading of both up and down counting functions. the borrow output pro- duces a negative going pulse when the counter under- flows and the carry outputs a pulse when the counter overflows. the counter can be cascaded by connecting the carry and borrow outputs of one device to the count up and count down inputs, respectively, of the next device. all inputs are equipped with protection circuits against static discharge and transient excess voltage. 1/15
