Overview
The SN74ALS30AD is an obsolete Texas Instruments component belonging to the ALS logic family. It contains a single 8-input positive-NAND gate within a 14-pin SOIC package. The device operates at a nominal supply voltage of 5 V, with a recommended range of 4.5 V to 5.5 V. It supports a commercial operating temperature range from 0°C to 70°C and implements the Boolean function Y = A • B • C • D • E • F • G • H.
Feature Summary
- Implements an 8-input positive-NAND logic function
- Utilizes Advanced Low-Power Schottky (ALS) technology for optimized performance
- Provides a single gate configuration in a compact surface-mount package
Applications
- Digital logic circuit design requiring multi-input NAND operations
- Microprocessor-based system interfacing
- General-purpose digital signal processing applications
Procurement Notes
Verify that the SN74ALS30AD is marked as obsolete in current catalogs. Confirm availability of active replacements such as the SN74ALS30ADR or SN74ALS30ADB before procurement. Ensure compatibility with existing board layouts and verify RoHS compliance requirements for the replacement part number.
Selection Notes
Select this component only if legacy support for the specific SOIC-14 form factor is required. Evaluate alternative packages like SSOP or Tape & Reel variants if manufacturing flexibility is needed. Consider the transition to newer logic families if power consumption or speed improvements are necessary for the target application.
Part Context
This device is part of the broader SN74ALS30A product line manufactured by Texas Instruments. It shares functional specifications with other members of the ALS series but differs in physical packaging. The 'D' suffix specifically denotes the Small Outline Integrated Circuit (SOIC) package type used in this variant.
Replacement Considerations
The SN74ALS30AD is listed as obsolete. Active substitutes include SN74ALS30ADR and SN74ALS30ADB. Verify pinout compatibility when transitioning between these active part numbers.
