SN74ALS02ANG4

Overview

The SN74ALS02ANG4 is a catalog-rated logic gate manufactured by Texas Instruments, belonging to the SN74ALS02A series. It implements quadruple 2-input positive-NOR logic functions within a single integrated circuit package. The device utilizes bipolar technology and features push-pull outputs designed for standard TTL compatibility. It operates reliably within a supply voltage range of 4.5 V to 5.5 V. The component supports a low-level output current of 8 mA and a high-level output current of -400 uA. Propagation delay is specified at 12 ns. It is housed in a 14-pin PDIP package suitable for through-hole mounting.

Feature Summary

• Implements quadruple 2-input positive-NOR logic functionality
• Utilizes bipolar ALS technology with push-pull outputs
• Supports standard 5 V logic system operation

Applications

• Digital logic circuit design
• Signal processing systems
• General-purpose computing hardware

Procurement Notes

Verify the G4 suffix indicates lead-free composition and RoHS compliance when sourcing. Confirm the 'A' designation ensures catalog rating availability rather than limited production status. Ensure the PDIP-14 package matches the target PCB footprint requirements for through-hole assembly processes.

Selection Notes

Select this component for designs requiring NOR logic gates with moderate speed characteristics. The ALS series offers improved performance over standard LS logic while maintaining pin compatibility. Verify that the 12 ns propagation delay meets the timing constraints of the specific application circuit before finalizing the bill of materials.

Part Context

This part belongs to the Texas Instruments SN74ALS02A family of advanced small-scale integration logic devices. The family provides enhanced switching speeds compared to earlier generations while retaining functional compatibility with standard TTL interfaces. The SN74ALS02 variant specifically focuses on NOR gate applications within digital logic architectures.

Replacement Considerations

SN74ALS02AN serves as a direct equivalent without the lead-free manufacturing designation.
