SN74HCS30PWR NAND Gate IC Equivalent & Substitute Parts

Part Overview

The SN74HCS30PWR is an active-status NAND Gate IC manufactured by Texas Instruments, featuring 1 channel with 8 inputs and Schmitt Trigger input capability. This component is housed in a 14-TSSOP surface mount package and operates across a 2V to 6V supply voltage range. The part is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when electrical characteristics, package specifications, and operational parameters remain identical across manufacturing grades or qualification levels. Alternative part numbers may be required due to inventory availability, application-specific certifications, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74HCS30PWR is determined by strict equivalence across the following parameters:

Electrical Equivalence Criteria:

• Logic type (NAND Gate)
• Number of circuits (1)
• Number of inputs (8)
• Schmitt Trigger input feature
• Supply voltage range (2V ~ 6V)
• Quiescent current maximum (2 µA)
• Output current specifications (7.8mA high and low)
• Input logic level thresholds (Low: 1V ~ 3V; High: 1.5V ~ 4.2V)
• Propagation delay (27ns @ 6V, 50pF)
• Operating temperature range (-40°C ~ 125°C)

Mechanical Equivalence Criteria:

• Package type (14-TSSOP)
• Physical dimensions (0.173", 4.40mm Width)
• Surface mount mounting type

Compliance Equivalence Criteria:

• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

The SN74HCS30QPWRQ1 meets all electrical, mechanical, and compliance requirements for direct substitution. The addition of automotive-grade qualification (AEC-Q100) and automotive designation does not preclude substitution in non-automotive applications, as automotive-qualified components maintain full compatibility with standard industrial specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SN74HCS30PWR and SN74HCS30QPWRQ1 are active-status components manufactured by Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on application requirements and compliance certifications.

SN74HCS30PWR is appropriate for standard industrial and consumer applications where automotive qualification is not required. This part maintains full ROHS3 compliance and unlimited moisture sensitivity rating.

SN74HCS30QPWRQ1 is designated for automotive applications and carries AEC-Q100 qualification. This part is suitable for use in automotive systems and meets automotive-grade reliability standards while maintaining identical electrical performance to the standard version. The automotive qualification does not restrict use in non-automotive applications.

Selection should be based on application environment, supply chain availability, and any specific qualification requirements mandated by the end-use system. Both parts are interchangeable from an electrical and mechanical standpoint.

Frequently Asked Questions (FAQ)

Q: Can the SN74HCS30QPWRQ1 be used as a direct replacement for the SN74HCS30PWR?

A: Yes. The SN74HCS30QPWRQ1 is electrically and mechanically equivalent to the SN74HCS30PWR. All electrical parameters, including supply voltage, quiescent current, output current, input logic levels, propagation delay, and operating temperature range are identical. Both parts use the same 14-TSSOP package with identical physical dimensions.

Q: What is the difference between these two part numbers?

A: The primary difference is the automotive-grade qualification. The SN74HCS30QPWRQ1 carries AEC-Q100 qualification and is designated as automotive-grade, while the SN74HCS30PWR is standard-grade. Both parts are manufactured by Texas Instruments and share the 74HCS30 base product number. The automotive qualification does not affect electrical performance or compatibility in non-automotive applications.

Q: Are the package specifications identical?

A: Yes. Both parts are housed in a 14-TSSOP surface mount package with dimensions of 0.173" by 4.40mm width. The physical footprint and mounting requirements are identical, allowing direct PCB substitution without layout modifications.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the SN74HCS30PWR and SN74HCS30QPWRQ1 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Both parts are suitable for applications requiring RoHS compliance.

Q: What is the operating temperature range for both parts?

A: Both parts operate across an identical temperature range of -40°C to 125°C, supporting applications in industrial, commercial, and automotive environments within this thermal specification.

Q: Can these parts be used interchangeably in automotive applications?

A: The SN74HCS30QPWRQ1 is specifically qualified for automotive use with AEC-Q100 certification. For automotive applications requiring formal qualification documentation, the SN74HCS30QPWRQ1 is the appropriate selection. The SN74HCS30PWR may be used in non-automotive or non-safety-critical automotive applications where automotive qualification is not mandated.

Q: What are the key electrical specifications that determine substitution eligibility?

A: Substitution is determined by equivalence in logic type (NAND Gate), circuit count (1), input count (8), Schmitt Trigger feature, supply voltage range (2V ~ 6V), quiescent current (2 µA maximum), output current (7.8mA), input logic thresholds, propagation delay (27ns @ 6V, 50pF), and operating temperature range (-40°C ~ 125°C).
