74VHC175MX Equivalent & Substitute Parts

Part Overview

The 74VHC175MX is a D-Type flip-flop logic integrated circuit manufactured by onsemi, designed for digital signal processing and sequential logic applications. This single-element, 4-bit positive edge-triggered flip-flop operates across a wide supply voltage range of 2V to 5.5V and features complementary outputs with master reset functionality. The device is currently in active production status and maintains full RoHS3 compliance. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory constraints require component alternatives.

Substitute Part Grouping Explanation

Substitute parts for the 74VHC175MX are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:

• Functional Type: D-Type flip-flop with 1 element and 4 bits per element
• Output Configuration: Complementary outputs with positive edge trigger
• Control Function: Master reset capability
• Package Compatibility: 16-SOIC (0.154", 3.90mm Width) surface mount package
• Voltage Range: Supply voltage operation within 2V to 5.5V
• Operating Temperature: -40°C to 85°C ambient temperature range
• Compliance: RoHS3 compliant, MSL Level 1

The SN74LV175ADR from Texas Instruments meets all these criteria and qualifies as a direct substitute. Both parts share identical package geometry, functional architecture, and environmental operating specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 74VHC175MX and SN74LV175ADR maintain active product status and full RoHS3 compliance, qualifying them for equivalent use in applications requiring D-Type flip-flop logic with 4-bit configuration and complementary outputs. The parts are mechanically and electrically interchangeable within the specified supply voltage range of 2V to 5.5V and operating temperature range of -40°C to 85°C.

Selection between these parts should be based on availability, lead time, and specific application requirements. The SN74LV175ADR offers higher maximum clock frequency (165 MHz versus 115 MHz) and greater output drive capability (12 mA versus 8 mA), while the 74VHC175MX provides lower quiescent current consumption (4 µA versus 20 µA). Both parts are suitable for direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the SN74LV175ADR replace the 74VHC175MX in existing designs?

A: Yes. Both parts share identical functional architecture, package geometry, and operating specifications. Direct substitution is possible without circuit redesign.

Q: Are there differences in electrical performance between these parts?

A: The parts differ in clock frequency rating (115 MHz versus 165 MHz), output drive current (8 mA versus 12 mA), quiescent current (4 µA versus 20 µA), and input capacitance (4 pF versus 1.4 pF). Propagation delay at 5V with 50pF load is identical at 9.3 ns for both parts.

Q: Is the 16-SOIC package identical for both parts?

A: Yes. Both parts use the 16-SOIC (0.154", 3.90mm Width) surface mount package with identical pin configuration and mechanical dimensions.

Q: Do both parts meet the same compliance standards?
