SN74ALS30ADB

Overview

The SN74ALS30ADB is an 8-input positive-NAND gate from the Texas Instruments ALS logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a low-level output current of up to 8 mA. The device functions in commercial temperature environments ranging from 0°C to 70°C. Propagation delays are specified with maximum values of 10 ns for high-to-low transitions and 12 ns for low-to-high transitions. It is housed in a 14-pin SSOP package.

Feature Summary

• Implements Boolean NAND logic using eight dedicated input terminals.
• Delivers standard TTL-compatible voltage levels for reliable interfacing.

Applications

• Digital logic circuit design
• Data acquisition systems
• Industrial control applications

Procurement Notes

Verify that the specific ordering suffix matches the required physical package dimensions and lead finish specifications. Confirm RoHS compliance status and moisture sensitivity level ratings prior to finalizing procurement orders to ensure compatibility with assembly processes.

Selection Notes

Select this component when an 8-input NAND function is required within the ALS series performance envelope. Ensure the application environment remains within the 0°C to 70°C operating temperature range. Verify that the 14-pin SSOP footprint aligns with the target printed circuit board layout constraints.

Part Context

This part belongs to the broader SN74ALS30A product family, which includes variants such as the SN74ALS30AD and SN74ALS30AN. These devices share identical internal logic structures but differ in packaging formats like SOIC or PDIP. The SN74ALS30ADB specifically utilizes the SSOP form factor for surface-mount integration.
