74HCT04D – NXP

Overview

The NXP 74HCT04D is a high-speed CMOS hex inverter designed for robust digital signal inversion. Its critical operational characteristic lies in its ability to achieve LSTTL-equivalent switching speeds while retaining the low power dissipation inherent to CMOS technology, making it ideal for power-sensitive applications. A key design consideration is its wide input voltage compatibility, allowing direct interfacing with TTL, NMOS, and other CMOS logic families, though careful attention must be paid to input capacitance when operating at very high frequencies to avoid signal integrity issues.

Key Features

• Hex Inverter configuration (6 independent inverters)
• High speed propagation delay: 8 ns (typ.) at VCC = 5 V
• Low static power consumption: 1.0 µA (max) at 25°C
• Wide operating temperature range: -40°C to 125°C
• TTL-compatible input voltage levels (VIH = 2.0 V min, VIL = 0.8 V max)
• TSSOP-14 package (7.0 x 4.4 x 1.2 mm)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Digital signal inversion in embedded control systems
• Logic level translation between TTL and High-Speed CMOS interfaces
