Substitute Part Grouping Explanation

Substitution of the CD40174BPWR is determined by strict equivalence across the following critical parameters:

• Functional Type: D-Type Flip Flop with 1 Element and 6 Bits per Element
• Electrical Performance: Clock Frequency of 16 MHz, Max Propagation Delay of 100ns @ 15V, 50pF
• Output Characteristics: Non-Inverted output type with 6.8mA output current (High and Low)
• Supply Voltage Range: 3V ~ 18V operation
• Quiescent Current: 4 µA maximum
• Package Specification: 16-TSSOP surface mount package with 0.173" width (4.40mm)
• Trigger Type: Positive Edge
• Function: Master Reset capability

The CD40174BPW is identified as a direct substitute based on identical electrical specifications, functional characteristics, and package configuration. The primary distinction is packaging format (Tube versus unspecified for the main part) and product status (Active versus Obsolete).
