will select four bits of data from either of two sources (Ports)
under control of a common Select input (S). The selected data
is transferred to a 4-bit output register synchronous with the
LOW-to-HIGH transition of the Clock input (CP). The 4-bit D-
GUARANTEED OPERATING RANGES
DC CHARACTERISTICS OVER OPERATING TEMPERATURE RANGE (unless otherwise specified)
NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under guaranteed operating ranges.
2. Not more than one output should be shorted at a time, nor for more than 1 second.

(I 0x , I 1x ) and Select input (S) must be stable only a setup time
prior to and hold time after the LOW-to-HIGH transition of the
Clock input for predictable operation.
