SN74LV32ANS Equivalent & Substitute Parts

Part Overview

The SN74LV32ANS is a 4-channel 2-input OR Gate logic integrated circuit manufactured by Texas Instruments. This device operates across a wide supply voltage range of 2V to 5.5V and is housed in a 14-SO surface mount package. The SN74LV32ANS carries a Last Time Buy product status, indicating that this specific packaging configuration is being discontinued. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs and long-term inventory planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LV32ANS is determined by strict equivalence across the following critical parameters:

Functional Equivalence: Logic type (OR Gate), number of circuits (4), and number of inputs per circuit (2) must remain identical.

Electrical Equivalence: Supply voltage range (2V ~ 5.5V), quiescent current (20 µA maximum), output current capabilities (12mA high and low), input logic thresholds (0.5V low, 1.5V high), and propagation delay (7.5ns @ 5V, 50pF) must match exactly.

Thermal Equivalence: Operating temperature range (-40°C ~ 125°C) must be maintained.

Physical Equivalence: Package type (14-SOIC with 0.209" width, 5.30mm) and mounting type (Surface Mount) must be identical to ensure PCB compatibility without redesign.

Compliance Equivalence: RoHS3 compliance and MSL rating (1 - Unlimited) must be preserved.

The SN74LV32ANSR qualifies as a direct substitute based on these criteria, with the primary difference being packaging format (Tape & Reel versus standard packaging) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The SN74LV32ANSR is a direct functional and electrical equivalent to the SN74LV32ANS. All critical electrical parameters, thermal specifications, and physical package dimensions are identical. Both devices are manufactured by Texas Instruments and maintain ROHS3 compliance with unlimited moisture sensitivity rating.

The primary distinction is product status and packaging format. The SN74LV32ANS is designated Last Time Buy, indicating limited future availability. The SN74LV32ANSR maintains Active product status with continuous manufacturing support. The SN74LV32ANSR is supplied in Tape & Reel format, which is standard for high-volume production environments and automated assembly processes.

For new designs or production transitions, the SN74LV32ANSR is the appropriate selection. For existing inventory management of the SN74LV32ANS, the SN74LV32ANSR provides seamless compatibility without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the SN74LV32ANSR replace the SN74LV32ANS in existing designs?

A: Yes. The SN74LV32ANSR is electrically and functionally identical to the SN74LV32ANS. All electrical parameters, operating ranges, and package dimensions match exactly. No circuit modifications or PCB redesign is required.

Q: What is the difference between SN74LV32ANS and SN74LV32ANSR?

A: The primary differences are product status and packaging format. The SN74LV32ANS is Last Time Buy with standard packaging. The SN74LV32ANSR is Active with Tape & Reel packaging, which is optimized for automated assembly and high-volume production.

Q: Are there any compatibility concerns with the 14-SOIC package?

A: No. Both parts use identical 14-SOIC packaging with 0.209" width and 5.30mm body dimensions. PCB footprints, solder pad layouts, and pick-and-place machine settings are fully compatible.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel is a delivery and handling format only. It does not affect electrical performance, reliability, or functional characteristics of the component.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74LV32ANS and SN74LV32ANSR are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the significance of Last Time Buy status?

A: Last Time Buy indicates that the SN74LV32ANS will no longer be manufactured after a specified date. Existing inventory is available, but future orders cannot be fulfilled. The SN74LV32ANSR should be used for new production to ensure long-term supply continuity.
