Overview
The SN74ALS808AFN is a hex 2-input AND driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal supply of 5.0 V. The device features totem-pole output configuration and contains six independent circuits per package. Each circuit accepts two inputs. The component is designed for surface mount installation and functions reliably across an operating temperature range from 0°C to +70°C.
Feature Summary
- Contains six independent 2-input AND logic gates in a single package
- Features totem-pole output configuration for direct interface capabilities
- Operates on a standard 5.0 V nominal supply voltage
Applications
- Digital logic signal processing
- Bus-oriented systems
- Memory address decoding
Procurement Notes
Verify the specific suffix 'AFN' against the official Texas Instruments datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the supplier provides documentation confirming the component is new original stock. Cross-reference the manufacturer part number with authorized distributor lists to validate authenticity before purchase.
Selection Notes
Select this component when a high-density solution requiring six independent AND gates is necessary. It is suitable for applications needing totem-pole outputs driven by ALS logic families. Consider the SOIC or similar surface-mount package constraints during PCB layout. Verify that the 5V supply rail stability meets the 4.5V to 5.5V operational limits for reliable switching.
Part Context
This part belongs to the SN74ALS series of advanced low-power Schottky logic devices. It serves as a specialized variant within the broader 74xx family, offering higher speed and lower power consumption compared to standard TTL. The 'AFN' designation typically indicates a specific package type and temperature grade offered by Texas Instruments for industrial applications.
Replacement Considerations
Direct substitutes include other SN74ALS08 variants such as SN74ALS08DR or SN74ALS08NSR, provided the package footprint matches. Verify pin compatibility carefully as package types may differ between DIP and SOIC formats.
