DM74LS298
Quad 2-Port Register Multiplexer with Storage
General Description
The DM74LS298 is a quad 2-port register. It is the logical
equivalent of a quad 2-input multiplexer followed by a quad
4-bit edge-triggered register. A Common Select input
selects between two 4-bit input ports (data sources). The
selected data is transferred to the output register synchro-
nous with the HIGH-to-LOW transition of the Clock input.
Features
s Select from two data sources
s Fully edge-triggered operation
s Typical power dissipation of 65 mW
