Substitute Part Grouping Explanation

Substitution of the MM74HC4514MTC is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must maintain 1 x 4:16 decoder/demultiplexer topology
• Package Type: Must be 24-TSSOP surface mount package with identical pinout
• Voltage Supply Range: Must support 2V ~ 6V operation
• Output Current Specifications: Must provide 5.2mA output capability for both high and low states
• Base Product Series: Must be 74HC4514 logic family member
• Mounting Technology: Must be surface mount compatible

The 74HC4514PW substitute meets all substitution criteria through identical circuit topology, package configuration, and electrical performance specifications. The primary distinction lies in product status and operating temperature range extension.
