Overview
The SN74ALS30AN is an 8-input positive-NAND gate from the Texas Instruments ALS logic family, housed in a 14-pin PDIP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range of 0°C to 70°C. The device performs the Boolean function Y = A • B • C • D • E • F • G • H. Propagation delay ranges from 3 ns to 12 ns depending on transition direction. Low-level output current is rated at 8 mA, with high-level output current at -0.4 mA.
Feature Summary
- Contains a single 8-input positive-NAND gate performing standard Boolean NAND logic functions.
- Utilizes Advanced Low-Power Schottky (ALS) technology for optimized power-speed performance.
- Accepts TTL-compatible input voltage levels across the full operating temperature range.
Applications
- Implementing complex logic decoding circuits requiring multiple input conditions.
- Constructing multi-stage logic gates where eight inputs must be combined into a single output.
- Building memory address decoders or control logic interfaces in digital systems.
Procurement Notes
Verify that the ordering suffix 'N' corresponds specifically to the PDIP package type. Confirm RoHS compliance status as indicated in the Package Option Addendum. Ensure the required operating temperature range matches the commercial grade specifications provided in the datasheet.
Selection Notes
Select this component when an 8-input NAND function is required within the ALS logic family. Consider the PDIP package if through-hole mounting is necessary for the application. Verify that the 8 mA low-level output current capability meets the load requirements of the connected circuitry.
Part Context
This part belongs to the SN74ALS30A series, which includes variants such as the SN74AS30A. While sharing similar logical functionality, the ALS variant offers different electrical characteristics compared to the AS series. The SN74ALS30AN represents the specific PDIP packaging option for the catalog version of this device.

FAQ
What is the Boolean function performed by the SN74ALS30AN?
The device performs the function Y = A • B • C • D • E • F • G • H, which is equivalent to Y = A + B + C + D + E + F + G in positive logic.
Does the SN74ALS30AN have three-state outputs?
No, the SN74ALS30AN is a standard logic gate without three-state outputs; it provides a direct NAND output based on its eight inputs.
