SN54/74LS298  
QUAD 2-INPUT MULTIPLEXER  
WITH STORAGE  
The SN54/74LS298 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 synchronous with the  
HIGH to LOW transition of the Clock input.  
QUAD 2-INPUT MULTIPLEXER  
WITH STORAGE  
LOW POWER SCHOTTKY  
The LS298 is fabricated with the Schottky barrier process for high speed  
and is completely compatible with all Motorola TTL families.  
Select From Two Data Sources  
Fully Edge-Triggered Operation  
Typical Power Dissipation of 65 mW  
Input Clamp Diodes Limit High Speed Termination Effects
