Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F175PC is determined by strict equivalence across the following critical parameters:

• Base product number (74F175 series)
• Functional configuration (1 element, 4-bit D-Type flip-flop with complementary output)
• Electrical specifications (140 MHz clock frequency, 8.5 ns propagation delay, 4.5V–5.5V supply)
• Trigger mechanism (positive edge)
• Package form factor (16-DIP through-hole)
• Output drive characteristics (1 mA high, 20 mA low)

The SN74F175N from Texas Instruments meets all these criteria, providing direct functional and electrical equivalence while maintaining identical pinout and package dimensions.
