74HCT04DB,112

Overview

The Nexperia 74HCT04DB,112 is a hex inverter integrated circuit belonging to 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 from -40 °C to +125 °C. The device features TTL-compatible input levels and CMOS low power dissipation. It provides high noise immunity and includes clamp diodes on inputs for interfacing with voltages exceeding VCC. The component is housed in a TSSOP14 plastic thin shrink small outline package (SOT402-1) containing 14 leads.

Feature Summary

• CMOS technology providing low power dissipation and high noise immunity
• TTL-compatible input levels ensuring direct interface with Transistor-Transistor Logic systems
• Input clamp diodes enabling current limiting resistor usage for voltages exceeding VCC
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Interface between TTL and CMOS logic domains

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the TSSOP14 package type. Confirm that the 74HCT variant matches the required TTL input voltage thresholds rather than standard HC CMOS levels. Ensure the selected component meets the specified industrial temperature range requirements for the target application environment.

Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS output drive characteristics. The wide operating temperature range makes it suitable for industrial environments. Verify that the TSSOP14 package dimensions fit the available PCB footprint constraints. Consider the propagation delay specifications relative to the maximum switching frequency of the intended digital system.

Part Context

This part belongs to the 74HCT04 series, which consists of six independent inverters. The 'DB' designation specifically identifies the TSSOP14 package variant manufactured by Nexperia. This series is designed to bridge the gap between older TTL logic standards and modern low-power CMOS technologies, offering robust performance in mixed-voltage digital systems.

Replacement Considerations

Direct replacements include other manufacturers' 74HCT04 devices in TSSOP14 packages. Cross-reference pinouts and electrical characteristics to ensure compatibility. Verify that any substitute component maintains the same latch-up performance and ESD protection ratings specified in the original datasheet.
