DM74ALS151N Equivalent & Substitute Parts

Part Overview

The DM74ALS151N is a 1 x 8:1 multiplexer logic integrated circuit manufactured by onsemi in a 16-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The DM74ALS151N operates with a single supply voltage between 4.5V and 5.5V, with output currents of 2.6mA (high) and 24mA (low), and supports operating temperatures from 0°C to 70°C. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS151N are qualified based on strict parametric equivalence across the following criteria:

• Circuit type and configuration (1 x 8:1 multiplexer)
• Independent circuit count (1)
• Output current specifications (2.6mA high, 24mA low)
• Single supply voltage operation (4.5V ~ 5.5V)
• Operating temperature range (0°C ~ 70°C)
• Through-hole mounting with 16-DIP package format (0.300", 7.62mm)
• 16-PDIP supplier device package designation

All substitute parts listed maintain these electrical and mechanical parameters, enabling direct functional replacement in applications designed for the DM74ALS151N.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—SN74ALS151N, SN74ALS251N, and SN74AS151N from Texas Instruments—are active products with full parametric equivalence to the obsolete DM74ALS151N. The Texas Instruments parts carry ROHS3 compliance certification, providing regulatory advantage for new designs and procurement cycles. The DM74ALS151N, being obsolete, presents supply chain risk; transitioning to any of the active Texas Instruments equivalents ensures long-term availability and compliance with current environmental standards.

Selection between the three Texas Instruments options depends on series preference: SN74ALS151N and SN74ALS251N operate within the 74ALS logic family, while SN74AS151N operates within the 74AS logic family. All maintain identical electrical performance and package specifications for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS151N, SN74ALS251N, and SN74AS151N be used interchangeably with DM74ALS151N?

A: Yes. All three parts maintain identical electrical parameters (output currents, supply voltage, operating temperature range) and mechanical specifications (16-DIP package, through-hole mounting). Direct pin-for-pin replacement is supported.

Q: What is the difference between SN74ALS151N and SN74ALS251N?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The difference lies in the base product number designation (74ALS151 versus 74ALS251), but functional performance and pin compatibility remain unchanged for this application.

Q: How does SN74AS151N differ from the SN74ALS151N?

A: SN74AS151N operates within the 74AS logic family, while SN74ALS151N operates within the 74ALS family. Both maintain identical output current specifications (2.6mA high, 24mA low), supply voltage (4.5V ~ 5.5V), and operating temperature range (0°C ~ 70°C). The series designation reflects internal logic family characteristics but does not affect substitution compatibility for this multiplexer function.

Q: Is the 16-DIP package compatible across all parts?

A: Yes. All parts use the 16-DIP (0.300", 7.62mm) package with 16-PDIP supplier designation, ensuring mechanical and pin compatibility for through-hole mounting applications.

Q: What compliance certifications apply to the substitute parts?

A: All Texas Instruments substitute parts carry ROHS3 compliance and REACH Unaffected status. Export classification (ECCN EAR99) and tariff code (HTSUS 8542.39.0001) are identical across all parts.
