74HCT00DB,118

Overview

The Nexperia 74HCT00DB,118 is a quad 2-input NAND gate belonging to the HCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device utilizes an SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. It supports an ambient operating temperature from -40 °C to +125 °C. Static characteristics include a maximum low-level output voltage of 0.4 V at 4 mA load and a high-level output voltage of 3.7 V at -4 mA load. Dynamic performance specifies a propagation delay of up to 29 ns at 4.5 V.

Feature Summary

• CMOS technology providing low power dissipation and high noise immunity
• TTL-compatible input levels for direct interfacing with Transistor-Transistor Logic systems
• Robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Integrated input clamp diodes allowing current limiting resistors for voltages exceeding VCC

Applications

• Digital signal processing logic circuits
• Microcontroller peripheral interface gating
• Memory address decoding networks
• General-purpose boolean logic implementation in industrial control systems

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS drive capabilities. The wide operating temperature range suits industrial environments. Ensure the SO14 footprint matches the PCB layout constraints. Confirm that the 4.5 V to 5.5 V supply range aligns with the system power rails.

Part Context

This part belongs to the 74HCT00 family of quad 2-input NAND gates manufactured by Nexperia. It shares functional compatibility with other standard logic families but offers distinct electrical characteristics defined by the HCT series specifications. The DB suffix indicates the specific SO14 surface-mount package variant.

Replacement Considerations

Cross-reference with other 74HCT00 variants in SO14 packages from different manufacturers if pinout compatibility is maintained. Verify equivalent propagation delays and output drive currents before substitution.
