FUNCTIONAL DESCRIPTION
The LS298 is a high speed Quad 2-Port Register. It selects
four bits of data from two sources (ports)under the control
of a Common Select Input (S). The selected data is
transferred to the 4-bit output register synchronous with the
HIGH to LOW transition of the Clock input (CP). The 4-bit
output register is fully edge-triggered. The Data inputs (I)
and Select input (S) must be stable only one setup time prior
to the HIGH to LOW transition of the clock for predictable
operation.
