Overview
The SN74ALS10AFN is a triple 3-input positive-NAND gate from Texas Instruments' Advanced Low-power Schottky (ALS) logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 11 ns. The device provides a low-level output current of 8 mA and a high-level output current of -400 uA. It is housed in a 20-lead Plastic Quad Flat Package (PQFP) with a 0.3-inch body width, suitable for surface-mount applications.
Feature Summary
- Advanced Low-power Schottky technology ensures high-speed operation while maintaining low power consumption.
- Triple 3-input NAND configuration allows complex logic functions within a single package.
- Surface-mount PQFP package facilitates automated assembly and compact circuit board design.
Applications
- High-speed digital logic circuits requiring low power dissipation
- Microprocessor-based systems for address decoding and control logic
- Memory interface circuits for data bus management
Procurement Notes
Verify the specific suffix 'FN' confirms the 20-lead PQFP package variant, distinct from the PDIP or SOIC versions. Confirm RoHS compliance status through the official datasheet as manufacturing updates may occur. Ensure the source document explicitly lists SN74ALS10AFN to avoid confusion with similar ALS series parts like SN74ALS10AN or SN74ALS10ANSR.
Selection Notes
Select this component when a surface-mount solution is required for ALS speed and power characteristics. Compare against SN74F10N if higher drive current is needed, noting the F series offers faster switching but higher power usage. Verify pin compatibility with existing footprints, as the PQFP package differs significantly from through-hole alternatives.
Part Context
This part belongs to the SN74ALS10A series, which standardizes TTL-compatible logic using advanced Schottky diodes. The ALS family bridges the gap between standard 74S performance and 74LS power efficiency. The AFN designation specifically identifies the quad flat package form factor used in modern electronics manufacturing.
Replacement Considerations
SN74ALS10AN (PDIP), SN74ALS10ANSR (SOIC). These are functionally equivalent but differ in package type. Direct pin-to-pin replacement requires matching the physical footprint constraints of the target PCB design.
