’HCT193 Synchronous Binary Counters
Typical Clear, Load, and Count Sequences
TL/F/5742–3
Sequence:
(1) Clear outputs to zero.
(2) Load (preset) to binary thirteen
(3) Count up to fourteen, fifteen, carry, zero, one, and two.
(4) Count down to one, zero, borrow, fifteen, fourteen, and thirteen.
Note A:
Clear overrides load data, and count inputs.
Note B:
When counting up, count-down input must be high; when counting down, count-up input must be high.
