Generally count
Down count at the rise edge of clock (CLK)
Down count at the fall edge of clock (CLK)
X
X
L
Synchronous preset
Jn data is preset at the rise of clock (CLK), the fall
of clock (CLK)
L
H
—
Initialize of Q output
Initialize of Q = “L”
H
Notes: 1. Synchronous preset (
SPE
) input can set max 256 down counts.
2. When the count value is 0, the next clock pulse presets the data to invert the output.
3. CLR and PR inputs initialize output state.
