Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC175NG4 is determined by strict equivalence across the following critical parameters:

• Logic Function: D-Type flip-flop with 1 element, 4-bit configuration, complementary output
• Trigger Characteristic: Positive edge triggering
• Electrical Performance: Clock frequency of 60 MHz, propagation delay of 26 ns @ 6V/50pF
• Voltage Specification: Supply voltage range 2V to 6V
• Output Characteristics: Output current capability of 5.2 mA (high and low)
• Package Configuration: 16-DIP (0.300", 7.62mm) through-hole mounting
• Compliance Standards: ROHS3 compliance, REACH unaffected status

The substitute part SN74HC175N meets all these criteria while differing only in packaging format (tube vs. standard packaging) and product status (active vs. discontinued).

Parameter Comparison

Engineering Selection Recommendations

The SN74HC175N is a direct functional equivalent to the SN74HC175NG4. Both devices share identical electrical specifications, logic function, and package configuration. The primary distinction is product status: the SN74HC175NG4 is discontinued, while the SN74HC175N maintains active status with established supply chain availability.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The SN74HC175N is suitable for new designs and replacement applications where the SN74HC175NG4 is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC175N be used as a direct replacement for the SN74HC175NG4?

A: Yes. Both devices are electrically and functionally identical. They share the same logic function (D-Type flip-flop, 1 element, 4-bit), electrical performance (60 MHz clock frequency, 26 ns propagation delay), supply voltage range (2V to 6V), output current capability (5.2 mA), and 16-DIP package configuration. The SN74HC175N is available with active product status.

Q: Are there any package or mounting differences between these parts?

A: Both parts use identical 16-DIP (0.300", 7.62mm) through-hole packaging. The primary difference is packaging format: the SN74HC175NG4 uses standard packaging, while the SN74HC175N is supplied in tube packaging. This does not affect electrical performance or board-level compatibility.

Q: Do both parts meet current compliance standards?

A: Yes. Both the SN74HC175NG4 and SN74HC175N are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the operating temperature range for these devices?

A: Both devices operate across the temperature range of -40°C to 85°C (TA), suitable for industrial and commercial applications.

Q: Are there any differences in quiescent current or power consumption?

A: No. Both devices have identical quiescent current specifications of 8 µA and identical output current capability of 5.2 mA for both high and low states.
