SN74LVC08AMDREP Equivalent & Substitute Parts

Part Overview

The SN74LVC08AMDREP is a 4-channel 2-input AND gate logic IC manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This active product operates across a 2V to 3.6V supply voltage range with low quiescent current consumption of 10 µA maximum. The device is designed for general-purpose logic applications requiring AND gate functionality with standard propagation delay characteristics. Substitute parts may be required due to inventory availability, packaging preferences, or manufacturer sourcing constraints while maintaining functional and electrical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC08AMDREP is determined by the following critical parameters:

Functional Requirements: All substitute parts must be 4-channel 2-input AND gate logic ICs with identical logic type and circuit configuration.

Electrical Compatibility: Supply voltage range, output current capability, and propagation delay characteristics must support the intended application. The main part operates at 2V ~ 3.6V with 4.1ns maximum propagation delay at 3.3V and 50pF load.

Package Compatibility: All parts must use 14-SOIC surface mount packaging with identical pin configuration and mechanical dimensions (0.154", 3.90mm width).

Compliance & Status: All substitute parts must maintain active product status and ROHS3 compliance to ensure long-term availability and regulatory adherence.

The three substitute parts listed below meet these criteria across different manufacturer offerings and packaging formats.

Parameter Comparison

Engineering Selection Recommendations

74LVC08AD,118 (Nexperia): This substitute offers the closest electrical match to the SN74LVC08AMDREP, with identical 4.1ns propagation delay and extended operating temperature range to -40°C. The wider supply voltage range (1.2V ~ 3.6V) provides additional design flexibility. ROHS3 compliance and active product status ensure regulatory alignment and long-term availability. Higher quiescent current (40 µA vs. 10 µA) should be evaluated for power-sensitive applications.

74LCX08M (Fairchild) and MC74LCX08DG (onsemi): Both parts share identical electrical specifications with 5.5ns propagation delay and 10 µA quiescent current. The 1.4ns propagation delay increase relative to the main part may impact timing-critical applications. Operating temperature range is limited to -40°C ~ 85°C. Both maintain ROHS3 compliance and active product status. These options are suitable for applications where the propagation delay difference is acceptable and operating temperature does not exceed 85°C.

All substitute parts maintain identical output current capability (24mA), package configuration (14-SOIC), and mounting type (surface mount), ensuring direct functional replacement within their specified electrical and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the 74LCX08M or MC74LCX08DG be used in applications requiring operation below -40°C?

A: No. Both the 74LCX08M and MC74LCX08DG are rated for -40°C minimum operating temperature, while the SN74LVC08AMDREP and 74LVC08AD,118 support -55°C. Applications requiring sub-40°C operation must use the SN74LVC08AMDREP or 74LVC08AD,118.

Q: What is the impact of the 1.4ns propagation delay difference between the main part and 74LCX08M/MC74LCX08DG substitutes?

A: The SN74LVC08AMDREP and 74LVC08AD,118 specify 4.1ns maximum propagation delay, while 74LCX08M and MC74LCX08DG specify 5.5ns. This 1.4ns difference must be evaluated against system timing margins. Applications with tight timing constraints should use the 4.1ns parts.

Q: Are all substitute parts pin-compatible with the SN74LVC08AMDREP?

A: Yes. All substitute parts use identical 14-SOIC packaging with the same pin configuration and mechanical dimensions (0.154", 3.90mm width), enabling direct board-level replacement.

Q: Does the higher quiescent current of the 74LVC08AD,118 affect power consumption significantly?

A: The 74LVC08AD,118 specifies 40 µA maximum quiescent current versus 10 µA for other parts. For battery-powered or ultra-low-power applications, this 30 µA difference should be evaluated against total system power budget. For standard applications, this difference is typically negligible.

Q: Which substitute part offers the widest supply voltage range?

A: The 74LVC08AD,118 supports 1.2V ~ 3.6V supply voltage, compared to 2V ~ 3.6V for the SN74LVC08AMDREP, 74LCX08M, and MC74LCX08DG. Applications requiring operation below 2V must use the 74LVC08AD,118.

Q: Are all substitute parts ROHS3 compliant?

A: The SN74LVC08AMDREP, 74LVC08AD,118, and MC74LCX08DG are ROHS3 compliant. ROHS compliance status for the 74LCX08M is not specified in available documentation.
