SN74ALS30ADR

Overview

The SN74ALS30ADR 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, with a nominal rating of 5 V. The device provides a low-level output current of 8 mA and a high-level output current of -2 mA. Propagation delay times are specified as 3 ns to 10 ns for low-to-high transitions and 3 ns to 12 ns for high-to-low transitions. It functions in commercial temperature environments ranging from 0°C to 70°C and is housed in a 14-pin SOIC package.

Feature Summary

• Performs Boolean NAND logic operations on eight distinct input signals
• Compatible with standard TTL voltage levels for inputs and outputs
• Delivers enhanced drive capability relative to standard LS logic families

Applications

• Digital logic circuit design requiring multi-input decision making
• Data bus monitoring systems
• Microprocessor address decoding networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's Package Option Addendum to confirm the exact physical package type and moisture sensitivity level. Confirm RoHS compliance status and lead finish specifications directly from the most recent production data documentation prior to procurement.

Selection Notes

Select this component when an 8-input NAND function is required within the ALS performance tier. Ensure the application environment remains within the 0°C to 70°C operating temperature range. Verify that the system power supply maintains stability between 4.5 V and 5.5 V to guarantee correct logic threshold operation.

Part Context

This part belongs to the broader SN74ALS30A product family, which includes variants in different packages such as PDIP and SSOP. The 'ADR' suffix specifically denotes the tape-and-reel packaging format for the SOIC-14 variant. Other family members include the military-grade SN54ALS30A and the faster SN74AS30 series.

FAQ

What is the maximum propagation delay for this device?

The maximum propagation delay is 12 ns for high-to-low transitions and 10 ns for low-to-high transitions under recommended operating conditions.

Does this device feature three-state outputs?

No, the SN74ALS30ADR contains a single 8-input NAND gate with standard totem-pole outputs and does not include an enable or control pin for tri-stating.
