SN74LVC08ANSRE4 Equivalent & Substitute Parts

Part Overview

The SN74LVC08ANSRE4 is a 4-channel AND gate logic IC manufactured by Texas Instruments, housed in a 14-SO surface mount package. This component is classified as discontinued at DiGi Electronics, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The part operates across a supply voltage range of 1.65V to 3.6V and is suitable for low-voltage digital logic applications requiring AND gate functionality with 2 inputs per channel.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC08ANSRE4 is determined by the following critical parameters:

• Logic Type: AND Gate with 4 channels and 2 inputs per channel
• Supply Voltage Range: Minimum 1.65V support required
• Output Current Capability: 24mA minimum for both high and low states
• Propagation Delay: Maximum 3.9ns at 3.3V with 50pF load
• Operating Temperature Range: -40°C to 125°C minimum
• Package Compatibility: 14-SOIC surface mount form factor
• RoHS Compliance: ROHS3 Compliant status

Parts meeting all these criteria are classified as parametric equivalents. Parts with minor deviations in non-critical parameters (such as quiescent current or packaging format) may serve as functional alternatives depending on application requirements.

Parameter Comparison

Engineering Selection Recommendations

SN74LVC08ANSR (Parametric Equivalent)

The SN74LVC08ANSR is a direct parametric equivalent to the SN74LVC08ANSRE4. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and maintain the same 14-SOIC package dimensions. The primary distinction is packaging format: SN74LVC08ANSR is supplied in Tape & Reel format versus the original part's standard packaging. This part carries Active product status and ROHS3 compliance, making it the preferred direct replacement for discontinued inventory.

74LCX08M (Functional Alternative)

The 74LCX08M, manufactured by Fairchild Semiconductor, provides AND gate functionality with identical circuit count and input configuration. However, this part exhibits deviations in critical parameters: minimum supply voltage is 2V (versus 1.65V), quiescent current is elevated at 10 µA, propagation delay is 5.5ns (versus 3.9ns), and operating temperature range is limited to -40°C to 85°C. This part is suitable only for applications where the higher minimum voltage, increased propagation delay, and reduced temperature range are acceptable. Package dimensions differ (0.154" versus 0.209" width), requiring PCB layout verification.

74LVC08AD,118 (Functional Alternative)

The 74LVC08AD,118, manufactured by Nexperia USA Inc., maintains the same logic configuration and output current specifications. This part offers extended supply voltage range (1.2V minimum) and identical operating temperature range. However, quiescent current is significantly higher at 40 µA, and propagation delay is 4.1ns. Input logic level thresholds differ, with lower minimum low-level input (0.12V) and lower minimum high-level input (1.08V). Package dimensions differ (0.154" versus 0.209" width). This part is Active and ROHS3 compliant, suitable for applications tolerating higher quiescent current and different input thresholds.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC08ANSR be used as a direct replacement for SN74LVC08ANSRE4?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, logic configuration, and package type. The only difference is packaging format (Tape & Reel versus standard). No circuit modifications are required.

Q: What are the key differences between 74LCX08M and the original part?

A: The 74LCX08M has a higher minimum supply voltage (2V versus 1.65V), higher quiescent current (10 µA versus 1 µA), slower propagation delay (5.5ns versus 3.9ns), and a narrower operating temperature range (-40°C to 85°C versus -40°C to 125°C). Package width also differs. Use this part only if your application tolerates these deviations.

Q: Is the 74LVC08AD,118 compatible with the original design?

A: The 74LVC08AD,118 provides the same logic function and output current capability. However, it has higher quiescent current (40 µA), different input logic level thresholds, and different package dimensions. Verify that your application can accommodate these parameter differences before substitution.

Q: Do all substitute parts have the same package footprint?

A: No. The SN74LVC08ANSR maintains the same 14-SOIC package dimensions (0.209" width) as the original. Both 74LCX08M and 74LVC08AD,118 use a narrower 14-SOIC package (0.154" width). PCB layout verification is required if using these alternatives.

Q: Are all substitute parts RoHS compliant?

A: SN74LVC08ANSR and 74LVC08AD,118 are both ROHS3 compliant. RoHS status for 74LCX08M is not specified in available documentation.

Q: Which substitute part is recommended for new designs?

A: Selection depends on application requirements. For direct replacement with no design changes, use SN74LVC08ANSR. For applications with relaxed timing requirements and different voltage specifications, evaluate 74LCX08M or 74LVC08AD,118 against your specific design constraints.
