Overview
The SN74AS00NS is a Texas Instruments logic gate featuring four independent 2-input positive-NAND gates. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device utilizes a 14-pin Small Outline (NS) package. Electrical characteristics include a maximum propagation delay of 4.5 ns at 5.5 V with a 50 pF load, a high-level output current capability of -2 mA, and a low-level output current capability of 20 mA.
Feature Summary
- Contains four independent 2-input NAND gates for Boolean logic operations
- Provides high-speed switching performance suitable for fast digital circuits
- Features standard TTL-compatible input and output voltage levels
Applications
- General-purpose digital logic processing
- Microprocessor system interface circuits
- Memory address decoding applications
Procurement Notes
Verify the specific ordering suffix 'NS' corresponds to the SOP-14 package configuration required for your design. Confirm that the RoHS status and lead finish meet your assembly specifications. Ensure the component meets the commercial temperature range requirements for your intended application environment before finalizing procurement.
Selection Notes
Select this component when high-speed NAND logic is required in a surface-mount format. Compare against SN74ALS00 variants if lower power consumption is prioritized over speed. Verify that the 14-pin SOP footprint aligns with your PCB layout constraints and that the 5V supply rail matches your system architecture.
Part Context
This part belongs to the Texas Instruments 74AS series of advanced Schottky logic devices. The 74AS family is characterized by significantly faster switching speeds compared to standard 74LS or 74S logic families. The SN74AS00 serves as a fundamental building block for complex digital systems requiring rapid logical decision-making capabilities.
