TECHNICAL DATA
IN74ACT193
Presettable 4-Bit Binary UP/DOWN Counter
High-Speed Silicon-Gate CMOS
The IN74ACT193 is identical in pinout to the LS/ALS192, HC/HCT192. The IN74ACT193 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 transitions on the clock inputs. This counter may be preset by entering the desired data on the P0, P1, P2, P3 input. When the Parallel Load input is taken low the data is loaded independently of either clock input.
