74AHCT00D,118

Overview

The Nexperia 74AHCT00D,118 is a quad 2-input NAND gate belonging to the AHCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level inputs. The device features overvoltage tolerant inputs up to 5.5 V, balanced propagation delays, and Schmitt-trigger action on all inputs. It is housed in an SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. The component supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• TTL-compatible input levels for direct interfacing with Transistor-Transistor Logic systems
• Overvoltage tolerant inputs allowing operation in mixed-voltage environments without external protection
• Schmitt-trigger action on all inputs to ensure high noise immunity and clean signal transitions

Applications

• Signal translation between TTL and CMOS logic domains
• Digital logic circuit design requiring quad NAND functionality
• Mixed-voltage system interconnects

Procurement Notes

Verify that the specific order suffix matches the required packaging configuration. Confirm the revision level against the latest product data sheet to ensure compliance with current JEDEC standards. Check for any recent Product Change Notifications regarding marking or assembly updates before finalizing procurement specifications.

Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS performance characteristics. The AHCT series provides balanced propagation delays suitable for general-purpose digital applications. Ensure the operating environment remains within the specified -40 °C to +125 °C temperature range and that the supply voltage does not exceed the maximum rating of 5.5 V.

Part Context

This part belongs to the Nexperia 74AHC/AHCT family of high-speed CMOS logic devices. The 'AHCT' designation specifically indicates TTL-compatible inputs while maintaining CMOS output drive capabilities. The 'D' suffix denotes the SO14 surface-mount package, distinguishing it from other form factors like TSSOP or QFN variants available within the same logical function family.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent quad 2-input NAND gates in the 74AHCT series. Verify pinout compatibility and electrical parameters such as propagation delay and output current drive before substitution.
