74HCT00DB,112

Overview

The Nexperia 74HCT00DB,112 is a quad 2-input NAND gate from the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL-compatible input levels and includes internal clamp diodes on all inputs. It provides four independent NAND gates in a single SOIC-14 (SOT108-1) package.

Feature Summary

• TTL-compatible input levels for direct interfacing with standard logic families
• CMOS low power dissipation characteristics
• High noise immunity performance
• Latch-up protection exceeding 100 mA per JESD 78 Class II Level B

Applications

• General-purpose digital logic applications requiring NAND functionality
• Industrial control systems operating at elevated temperatures
• Automotive electronics utilizing non-automotive qualified components where specified
• Consumer electronic devices requiring high noise immunity

Procurement Notes

Verify component authenticity through authorized distributors or official Nexperia channels. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with RoHS directives and REACH regulations prior to integration into final assemblies.

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS power efficiency. The wide operating temperature range makes it suitable for industrial environments. Verify that the SOIC-14 package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the 74HCT series, which bridges HC technology with TTL standards. The 'DB' suffix indicates the SOIC-14 plastic small outline package variant. It is functionally equivalent to other 74HCT00 variants but differs in physical packaging and thermal characteristics.

Replacement Considerations

Direct replacements include the 74HCT00D,112 from the same manufacturer. Cross-vendor equivalents must be verified for pin compatibility and electrical specifications.
