PIN DESCRIPTION
Both the A bus and the B bus are inputs
The Output functions of the A and B bus are disabled
Both the A and B bus are used for inputs to the internal
flip-flops. Data at the bus will be stored on low to high
transition of the clock inputs.
The A bus are outputs and the B bus are inputs
The data at the B bus are displayed at the A bus
The data at the B bus are displayed at the A bus. The
data of the B bus are stored to internal flip-flop on low
to high transition of the clock pulse
The data stored to the internal flip-flop are displayed at
the A bus.
The data at the B bus are stored to the internal flip-flop
on low to high transition of the clock pulse. The states
of the internal flip-flops output directly to the A bus.
The data at the A bus are displayed at the B bus
The data at the A bus are displayed at the B bus. The
data of the A bus are stored to the internal flip-flop on
low to high transition of the clock pulse.
The data stored to the internal flip-flops are displayed
at the B bus
The data at the A bus are stored to the internal flip-flop
on low to high transition of the clock pulse. The states
of the internal flip-flops output directly to the B bus.
