Overview
The SN74ALS00ADG4 is a quad 2-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 8 mA with a high-level output current of -400 uA. The device features a propagation delay of 11 ns and functions reliably across an operating temperature range of 0°C to +70°C. It is housed in a 14-pin SOIC package.
Feature Summary
- Contains four independent 2-input NAND gates for complex logic implementation
- Utilizes Advanced Low-Power Schottky technology for high-speed operation
- Provides push-pull outputs capable of driving standard TTL loads
Applications
- General-purpose digital logic circuits
- Signal gating and switching applications
- Data acquisition systems requiring fast response times
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance status according to manufacturer documentation. Confirm that the SOIC-14 package dimensions match the target PCB footprint requirements. Ensure the component meets the required industrial temperature specifications for the intended operational environment before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring multiple NAND gates with moderate speed and standard drive capability. The ALS series offers a balance between power consumption and performance suitable for general digital applications. Verify compatibility with existing system voltage levels and ensure adequate thermal management for the SOIC package configuration.
Part Context
This part belongs to the SN74ALS00A series, representing a widely used standard logic family. The 'G4' suffix typically denotes environmental compliance attributes such as lead-free manufacturing processes. It serves as a fundamental building block in digital electronics, providing essential logical inversion and combination functions for microprocessor interfaces and control logic.
Replacement Considerations
Direct replacements include the SN74ALS00AD variant, which shares identical electrical characteristics but may differ in packaging or environmental compliance details. Cross-reference datasheets to confirm pinout compatibility and functional equivalence before substituting components in existing designs.
