Overview
The SN74ALS1804AN is a hex 2-input NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the Advanced Low-power Schottky (ALS) logic family, providing high-speed performance with low power consumption. The device features six independent NAND gates within a single package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports propagation delays typical for ALS technology. The component is designed for surface-mount or through-hole applications depending on the specific variant, though this model utilizes a standard plastic dual-in-line package suitable for general-purpose digital logic circuits.
Feature Summary
- Hex configuration containing six independent 2-input NAND gates
- Advanced Low-power Schottky (ALS) technology for optimized speed-power product
- Standard TTL-compatible input and output characteristics
Applications
- General-purpose digital logic processing
- Boolean logic implementation in control systems
- Signal gating and switching applications
Procurement Notes
Verify the exact package type and pinout compatibility with your PCB footprint before integration. Confirm that the supply voltage requirements align with your system's 5V rail specifications. Check for any specific handling instructions regarding electrostatic discharge during assembly. Ensure that the manufacturer's datasheet is consulted for detailed electrical characteristics and thermal management guidelines relevant to your operating environment.
Selection Notes
Select this component when multiple independent NAND functions are required in a compact form factor. The ALS series offers a favorable balance between switching speed and power dissipation compared to standard TTL. Consider the physical package constraints and ensure that the board layout accommodates the specific lead pitch and dimensions defined in the mechanical drawings provided by the manufacturer.
Part Context
This part is part of the broader SN74ALS series of logic ICs from Texas Instruments. The series is known for its improved performance over earlier LS TTL families while maintaining backward compatibility. The SN74ALS1804AN specifically addresses designs requiring multiple NAND gates without consuming excessive board space or power budget.
Replacement Considerations
Compatible substitutes include other hex NAND gates from the same ALS family, such as the SN74ALS00N. Verify pin-to-pin compatibility and logical equivalence before substitution. Ensure that any alternative component meets the same voltage and temperature operating ranges.
