TECHNICAL DATA KK74ACT192 Presettable BCD, Decade UP, DOWN Counter High-Speed Silicon-Gate CMOS The KK74ACT192 is identical in pinout to the LS, ALS192, HC, HCT192. The KK74ACT192 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The counter has two separate clock inputs, a Count Up Clock and Count Down Clock inputs. The direction of counting is determined by which input is clocked. The outputs change state synchronous with the LOW-to-HIGH transi
