74ACT11004N

Overview

The Texas Instruments 74ACT11004N is a hex inverter integrated circuit belonging to the 74ACT logic family. It features six independent inverters within a single package, utilizing CMOS technology with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 9.7 ns. It provides high drive capability with output currents of ±24 mA. The component is housed in a TSSOP-20 surface-mount package and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Hex inverter configuration providing six independent signal inversion channels
• TTL-compatible input thresholds allowing direct interfacing with TTL logic systems
• High-speed performance characterized by low propagation delay times
• Robust output drive capability supporting significant capacitive loads

Applications

• Signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Data bus buffering and level shifting
• General-purpose logic functions in industrial control systems

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature rating. Ensure compatibility with existing PCB footprints, as variations exist between DIP, SOIC, and TSSOP formats. Confirm RoHS compliance status if required by project specifications. Cross-reference manufacturer part numbers to avoid confusion with similar AC or HC series components that may have different electrical characteristics.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output levels. The 74ACT series offers faster switching speeds compared to standard HC devices while maintaining compatible input thresholds. Consider the TSSOP-20 package for space-constrained surface-mount designs. Evaluate power consumption and noise immunity requirements, as ACT devices provide improved noise margins over older technologies suitable for high-density digital applications.

Part Context

This component is part of the broader 74ACT logic family, designed to bridge the gap between legacy TTL systems and modern CMOS technology. It shares functional similarities with other hex inverters but distinguishes itself through optimized speed and drive strength. The 74ACT series is widely used in telecommunications and computing infrastructure where reliable signal integrity and fast response times are critical for system performance.

Replacement Considerations

Public confirmed substitute part numbers include SN74ACT11004PW and SN74ACT11004DW. Verify pinout compatibility and electrical specifications before substitution.
