Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC163MT is determined by strict equivalence across the following critical parameters:

• Logic Type: Binary Counter (identical functional classification)
• Number of Bits per Element: 4 Bit (identical bit width)
• Count Rate: 24 MHz (identical maximum frequency specification)
• Trigger Type: Positive Edge (identical edge sensitivity)
• Reset: Synchronous (identical reset behavior)
• Timing: Synchronous (identical timing architecture)
• Voltage - Supply: 2 V ~ 6 V (identical supply voltage range)
• Operating Temperature: -55°C ~ 125°C (identical temperature range)
• Package / Case: 16-SOIC (0.154", 3.90mm Width) (identical physical footprint and pin count)
• Mounting Type: Surface Mount (identical mounting technology)

The substitute part CD74HC163M96 meets all these criteria and is therefore a direct parametric equivalent.
