SN74AS30NSR

Overview

The SN74AS30NSR is an 8-input positive-NAND gate from the Texas Instruments AS logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a high-level output current of -2 mA and a low-level output current of 20 mA. Propagation delay ranges from 1 ns to 5 ns for tPLH and 1 ns to 4.5 ns for tPHL. The device functions across commercial temperatures from 0°C to 70°C and is housed in a 14-pin SOIC package.

Feature Summary

• Performs Boolean NAND logic on eight independent inputs
• Provides high-speed switching capabilities with nanosecond propagation delays
• Features robust low-level output drive capability

Applications

• Digital logic circuit design requiring multi-input NAND functionality
• High-speed data processing systems
• Microprocessor-based control interfaces

Procurement Notes

Verify that the specific part number matches the required package type, as the 'NSR' suffix indicates a SOIC tape-and-reel configuration. Confirm RoHS compliance status and lead finish details against the latest Package Option Addendum. Ensure the operating temperature range aligns with system requirements, as catalog versions may differ from military specifications.

Selection Notes

Select this component when an 8-input NAND function is necessary within standard 5V logic systems. The AS series offers faster performance compared to LS or ALS counterparts. Verify pinout compatibility if replacing legacy parts, noting that unused inputs must be managed according to datasheet guidelines to prevent floating states.

Part Context

This device belongs to the SN74AS30 product line, which includes variants such as SN74ALS30A and SN54AS30. These components share similar logical functions but differ in speed, power consumption, and temperature ratings. The SN74AS30 represents the commercial-grade, high-speed variant within this specific family grouping.
