Description
Presettable 4-bit Binary Up/down Counter

Presettable 4-Bit Binary UP/DOWN Counter
High-Speed Silicon-Gate CMOS
HC/HCT192. The IN74ACT193 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
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. This feature allows the counters
to be used as devide-by-n by modifying the count lenght with the
preset inputs. In addition the counter can also be cleared. This is
accomplished by inputting a high on the Master Reset input. All 4
internal stages are set to low independently of either clock input.Both
a Terminal Count Down (TC
Outputs are provided to enable cascading of both up and down
counting functions. The TC
