Description : Quad 2-Input Multiplexer with Storage

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

Description : Quad 2-Input Multiplexer WITH 3-STATE OUTPUTS

Quad 2-Input Multiplexer WITH 3-STATE OUTPUTS

The MC74F258A is a Quad 2-Input Multiplexer with 3-state outputs. Four bits of data from two sources can be selected using a common Data Select input. The four outputs present the selected data in the complement (inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.

Multiplexer Expansion by Tying Outputs Together
• Inverting 3-State Outputs
• AC Enhanced Version of the F258
