Overview
The SN74ALS02ANS is a quadruple 2-input positive-NOR gate from the Texas Instruments ALS logic series. 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 12 ns and functions reliably across an operating temperature range of 0°C to +70°C. It is housed in a 14-pin SOIC package designed for surface-mount installation.
Feature Summary
- Contains four independent 2-input NOR logic gates within a single integrated circuit
- Utilizes Advanced Low-power Schottky (ALS) technology for optimized speed and power consumption
- Provides push-pull outputs capable of driving standard TTL loads
Applications
- Digital logic signal processing and Boolean operations
- General-purpose combinational logic circuits
- Industrial control systems requiring reliable NOR functionality
Procurement Notes
Verify that the part number suffix 'ANS' corresponds to the specific SOIC-14 package variant required for your design. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the exact pinout and electrical specifications defined in the official datasheet to prevent compatibility issues.
Selection Notes
Select this component when a compact solution for multiple NOR operations is needed in surface-mount designs. The ALS series offers a balance of switching speed and power efficiency suitable for general digital applications. Consider the 14-pin SOIC footprint constraints during PCB layout planning to ensure adequate spacing and thermal management for the chosen package type.
Part Context
This component belongs to the SN74ALS02A family, which includes variants such as the SN74ALS02AN (PDIP) and SN74ALS02NS (SOIC). The 'ANS' designation specifically identifies the non-transparent plastic small-outline package version manufactured by Texas Instruments. It serves as a direct functional replacement for older 74LS02 equivalents while providing improved performance characteristics.
Replacement Considerations
The SN74ALS02AN is a verified through-hole alternative offering identical logical function and electrical parameters. Designers requiring leaded packages may substitute this surface-mount component with the PDIP variant without altering circuit functionality.
