SN74AHCT00NSRG4

Overview

The SN74AHCT00NSRG4 is a quad 2-input positive-NAND gate from the Texas Instruments SN74AHCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features CMOS technology with TTL-compatible inputs. The device is housed in a 14-pin SOIC package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides four independent 2-input NAND logic functions
• Features TTL-compatible input thresholds for direct interfacing with TTL systems
• Utilizes advanced CMOS technology for low power consumption

Applications

• General-purpose digital logic applications
• Signal buffering and switching circuits
• Data acquisition systems requiring TTL compatibility

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green manufacturing status as defined by Texas Instruments. Confirm the package type matches the required PCB footprint, as variations exist within the AHCT family. Ensure the operating environment remains within the specified thermal limits for reliable performance.

Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS output drive capabilities. The AHCT series bridges the gap between older TTL logic families and modern CMOS processes. Consider the SOIC package constraints regarding pin pitch and board space availability during layout planning.

Part Context

This part belongs to the SN74AHCT logic family, which combines the high speed of AHC technology with the input compatibility of HCT devices. It serves as a standard solution for replacing legacy 74LS00 equivalents in modern designs while maintaining lower power dissipation and improved noise margins compared to older bipolar technologies.

Replacement Considerations

SN74AHCT00DRG4: Different package (SOIC-14 vs SOIC-14 narrow). SN74AHCT00DBRG4: Different package (SSOP-14). Verify pinout compatibility before substitution.
