SN74HCU04NSR

Inverter Gates Overview

The SN74HCU04NSR is a catalog hex inverter from the SN54HCU04/SN74HCU04 family, manufactured by Texas Instruments. It contains six independent inverters performing the Boolean function Y = A in positive logic. The device operates within a supply voltage range of 2 V to 6 V and supports an operating free-air temperature range of -40°C to 85°C. It features unbuffered outputs capable of driving up to 10 LSTTL loads with ±4-mA output drive at 5 V. Typical propagation delay is 7 ns, with maximum values reaching 20 ns at 6 V. Static power consumption is low, with a maximum ICC of 20 µA.

Inverter Gates Feature Summary

• Contains six independent inverters for Boolean inversion functions
• Supports wide operating voltage range from 2 V to 6 V
• Features unbuffered outputs compatible with LSTTL loads
• Provides low static power consumption with high input impedance

Inverter Gates Applications

• General-purpose digital logic signal inversion
• Clock signal generation and conditioning
• TTL-to-CMOS level translation interfaces
• Digital circuit buffering and waveform shaping

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'SR' corresponds to the SOP (NS) package and large tape-and-reel carrier configuration. Confirm RoHS compliance status and lead finish specifications against the latest TI Package Option Addendum. Ensure procurement channels provide valid traceability documentation for the active production status part number.

Inverter Gates Selection Notes

Select this component when six independent inverters are required in a surface-mount SOP-14 package. The HCU series offers faster switching speeds compared to standard HC devices while maintaining CMOS compatibility. Verify that the application environment remains within the specified -40°C to 85°C temperature range and utilizes supply voltages between 2 V and 6 V.

Inverter Gates Part Context

This device belongs to the SN54HCU04/SN74HCU04 family of high-speed CMOS logic circuits. The 'SN74' prefix indicates commercial grade temperature ratings, distinguishing it from the military-grade 'SN54' variant. The 'HCU' designation identifies the technology as High-Speed CMOS Unbuffered, optimized for speed and low power dissipation without internal buffering stages.

Inverter Gates Replacement Considerations

Direct functional equivalents include SN74HCU04DR (SOIC package) and SN74HCU04PWR (TSSOP package). Cross-reference pinouts and thermal characteristics when substituting packages. Verify that alternative parts maintain the same unbuffered output structure and voltage tolerance limits.
