Overview
The SN74AS30N is an 8-input positive-NAND gate from the AS series, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a recommended nominal voltage of 5 V. The device features a propagation delay (tPLH/tPHL) ranging from 1 ns to 5 ns depending on input/output transitions. It provides a low-level output current (IOL) of 20 mA and a high-level output current (IOH) of -2 mA. The component is housed in a 14-pin PDIP package and functions across an operating temperature range of 0°C to 70°C.
Feature Summary
- Performs Boolean NAND logic operations with eight distinct inputs
- Delivers high-speed switching characteristics typical of the AS logic family
- Provides robust output drive capabilities for standard TTL loads
Applications
- Digital logic circuit design requiring multi-input decision making
- Data processing systems utilizing standard 5V logic levels
- Industrial control applications compatible with commercial temperature ranges
Procurement Notes
Verify that the specific orderable part number matches the required package type and temperature grade. Confirm RoHS compliance status and lead finish specifications against the latest Package Option Addendum. Ensure the supplier provides documentation confirming the component meets the absolute maximum ratings and electrical characteristics defined in the official datasheet.
Selection Notes
Select this component when an 8-input NAND function is required with high-speed performance. Compare the AS series speed and power consumption against ALS or F series alternatives if lower power or different packaging options are necessary. Verify that the 20 mA output current capability aligns with the load requirements of the downstream circuitry.
Part Context
This device belongs to the Texas Instruments SN74AS30 product line, which includes variants such as SN74ALS30A and military-grade SN54AS30. These components share the same logical function but differ in speed, power consumption, and environmental operating ranges. The SN74AS30N specifically represents the commercial grade version in a plastic dual in-line package.

FAQ
What is the Boolean function performed by the SN74AS30N?
The device performs an 8-input positive-NAND operation, where the output is low only when all eight inputs are high.
Does the SN74AS30N have tri-state outputs?
No, the SN74AS30N has a standard totem-pole output structure without tri-state or open-collector configurations.
