Quad 2-Input Multiplexer with Storage
The SN74LS298 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.
The LS298 is fabricated with the Schottky barrier process for high speed and is completely compatible with all ON Semiconductor 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
