SN74LS132D Equivalent & Substitute Parts

Part Overview

The SN74LS132D is a NAND Gate IC featuring 4 channels with 2 inputs per channel and integrated Schmitt Trigger functionality, packaged in a 14-SOIC surface mount configuration. Manufactured by Texas Instruments, this component operates within the 74LS logic family and is currently designated as Last Time Buy status. The need for equivalent and substitute parts arises from inventory availability, packaging format requirements, or performance specification alignment with specific application demands.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LS132D is determined by the following critical parameters:

Functional Equivalence: All substitute parts must maintain identical logic type (NAND Gate), circuit count (4 channels), and input configuration (2 inputs per channel).

Package Compatibility: All parts must use the 14-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width) to ensure PCB layout compatibility without redesign.

Electrical Specifications: Supply voltage range, quiescent current, output current ratings, input logic levels, and propagation delay characteristics determine functional interchangeability within system constraints.

Compliance & Status: RoHS3 compliance and MSL rating (1 - Unlimited) are maintained across all qualified substitutes.

The SN74LS132DR qualifies as a direct manufacturer-recommended substitute with identical electrical specifications and packaging, differentiated only by tape and reel packaging format. The SN74ACT00D represents a cross-family alternative within the 74-series logic portfolio, offering enhanced performance characteristics with trade-offs in supply voltage range and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

SN74LS132DR is the primary substitute for SN74LS132D. Both parts maintain identical electrical specifications, operating temperature range, and Schmitt Trigger functionality. The SN74LS132DR is currently in Active product status with significantly higher inventory availability (105,815 pcs vs. 1,477 pcs), making it the preferred choice for new designs and replenishment orders. The only differentiation is packaging format: SN74LS132D is supplied in Tube packaging, while SN74LS132DR is supplied in Cut Tape and Digi-Reel format. Both are ROHS3 compliant with MSL rating of 1 (Unlimited).

SN74ACT00D is a cross-family alternative that maintains functional equivalence (4-channel NAND gate, 14-SOIC package) but introduces specification differences that require system-level evaluation. The 74ACT family offers superior propagation delay performance (9ns vs. 22ns), lower quiescent current (2µA vs. 11mA), and higher output current capability (24mA vs. 8mA). However, the SN74ACT00D operates across a wider supply voltage range (4.5V ~ 5.5V) and extended temperature range (-40°C ~ 85°C), and is currently discontinued at DiGi Electronics. Selection of SN74ACT00D requires confirmation that system design accommodates the different input logic level thresholds (0.8V/2V vs. 0.5V/1.9V) and that the absence of Schmitt Trigger functionality does not impact circuit performance.

Frequently Asked Questions (FAQ)

Q: Can SN74LS132DR be used as a direct replacement for SN74LS132D?

A: Yes. Both parts are electrically identical with matching supply voltage (4.75V ~ 5.25V), quiescent current (11 mA max), propagation delay (22ns @ 5V, 15pF), and operating temperature range (0°C ~ 70°C). The only difference is packaging format: tube versus cut tape/reel. PCB layout and circuit performance remain unchanged.

Q: What are the key differences between SN74LS132D and SN74ACT00D?

A: Both are 4-channel NAND gates in 14-SOIC packages, but they belong to different logic families with distinct electrical characteristics. SN74ACT00D offers faster propagation delay (9ns vs. 22ns), lower power consumption (2µA quiescent vs. 11mA), and higher output current (24mA vs. 8mA). However, SN74ACT00D lacks Schmitt Trigger functionality, operates across a wider voltage range (4.5V ~ 5.5V), and has different input logic level thresholds. Selection requires system-level compatibility verification.

Q: Is the 14-SOIC package identical across all three parts?

A: Yes. All three parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package with identical physical dimensions and pin configuration. No PCB redesign is required for package compatibility.

Q: What is the current availability status of these parts?

A: SN74LS132DR is in Active status with 105,815 pcs in stock. SN74LS132D is Last Time Buy with 1,477 pcs in stock. SN74ACT00D is Discontinued at DiGi Electronics with 2,110 pcs in stock. For new designs, SN74LS132DR is the recommended choice based on product status and inventory availability.

Q: Are all three parts RoHS3 compliant?

A: Yes. SN74LS132D, SN74LS132DR, and SN74ACT00D are all ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).
