Product specification
Presettable synchronous 4-bit binary
up/down counter
74HC/HCT193
Fig.5 Typical clear, load and count sequence.
(1) Clear overrides load, data and
count inputs.
(2) When counting up the count down
clock input (CP
) must be HIGH,
when counting down the count up
clock input (CP
U
) must be HIGH.
Sequence
Clear (reset outputs to zero);
load (preset) to binary thirteen;
count up to fourteen, fifteen,
terminal count up, zero, one
and two;
count down to one, zero,
terminal count down, fifteen,
