Quad 2-Input Multiplexer with Storage
Description
This device is a high-speed multiplexer with storage. 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 register is fully edge
triggered. The Data inputs (I
0
and I
1
) and Select input (S) must be stable only one setup time prior to the
HIGH-to-LOW transition of the clock for predictable operation.
Features
Outputs Source/Sink 24 mA
