• Common select lines for synchronized operation
• Separate output enable controls for each multiplexer
• High-speed CMOS technology for low power consumption

Applications

• Data routing in communication systems
• Signal selection in measurement equipment
• Address decoding in microprocessor interfaces
• Multiplexed display drivers

Procurement Notes

Verify the exact ordering suffix matches the required package variant, as suffixes may indicate tape-and-reel or cut-tape packaging options. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for your assembly process. Ensure the manufacturer part number corresponds to the specific pinout and electrical characteristics documented in the official datasheet.

Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required with common address lines. Consider the operating voltage range of 2V to 6V for compatibility with your system logic levels. Evaluate the propagation delay specifications against your timing requirements. Verify that the 16-pin SOIC package fits your PCB layout constraints.

Part Context

This component belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. The 74HC family offers wide voltage operation and compatibility with standard TTL logic levels. The CD74HC253M specifically provides dual multiplexer functionality within this established logic family, ensuring interoperability with other HC-series components in complex digital designs.

Replacement Considerations

Check for direct pin-compatible alternatives from Texas Instruments or other manufacturers offering equivalent 74HC dual 4-to-1 multiplexer specifications. Verify that any substitute maintains the same voltage range, package dimensions, and electrical performance characteristics.
