Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74HCS153DR is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Circuit type and configuration (2 x 4:1 multiplexer)
• Number of independent circuits (2)
• Output current specifications (7.8mA high and low)
• Voltage supply range (2V ~ 6V)
• Operating temperature range (-40°C ~ 125°C)

Mechanical Parameters:

• Package type (16-SOIC)
• Package dimensions (0.154", 3.90mm width)
• Mounting type (Surface Mount)
• Supplier device package (16-SOIC)

Compliance Parameters:

• Base product number (74HCS)
• Moisture sensitivity level (MSL 1)
• RoHS status (Not applicable)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The SN74HCS153QDRQ1 satisfies all substitution requirements while adding automotive-grade qualification (AEC-Q100).

Parameter Comparison

Engineering Selection Recommendations

SN74HCS153DR is the standard industrial-grade variant suitable for general commercial and industrial applications. Both the main part and substitute maintain Active product status with continuous manufacturing support from Texas Instruments.

SN74HCS153QDRQ1 is the automotive-qualified equivalent, carrying AEC-Q100 certification. This variant is appropriate for applications requiring automotive-grade reliability and qualification documentation. The automotive qualification does not alter electrical or mechanical specifications; it represents additional process controls and testing during manufacturing.

Selection between these parts depends on application requirements:

• Use SN74HCS153DR for standard industrial applications without automotive qualification requirements
• Use SN74HCS153QDRQ1 for automotive applications or systems requiring AEC-Q100 compliance

Both parts are functionally interchangeable at the circuit level due to identical electrical parameters, circuit configuration, and package specifications.

Frequently Asked Questions (FAQ)

Q: Can SN74HCS153QDRQ1 replace SN74HCS153DR in existing designs?

A: Yes. The SN74HCS153QDRQ1 is a direct parametric equivalent with identical electrical specifications, output current ratings, voltage supply range, operating temperature range, and 16-SOIC package dimensions. Pin configuration and functional behavior are identical.

Q: What is the difference between these two parts?

A: The primary difference is qualification level. SN74HCS153QDRQ1 carries AEC-Q100 automotive qualification, indicating compliance with automotive reliability and testing standards. Electrical and mechanical specifications are identical.

Q: Are both parts available in the same packaging?

A: Yes. Both parts use 16-SOIC surface mount packaging with identical dimensions (0.154", 3.90mm width). Both are supplied in Tape & Reel (TR) format.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These parts have unlimited shelf life under normal storage conditions and do not require special moisture control during handling or storage.

Q: Can I use SN74HCS153DR in an automotive application?

A: SN74HCS153DR lacks automotive qualification. For automotive applications requiring AEC-Q100 compliance, use SN74HCS153QDRQ1.

Q: Are there any pin or footprint differences between these parts?

A: No. Both parts use identical 16-SOIC package specifications with the same pin configuration and footprint dimensions.

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

A: Both parts operate across -40°C to 125°C, suitable for industrial and automotive temperature environments.

Q: Are both parts RoHS compliant?

A: RoHS status is listed as "Not applicable" for both parts, indicating they fall outside standard RoHS classification scope.
