SN74HC04N

Overview

The SN74HC04N is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74HC logic family. It contains six independent inverters performing the Boolean function Y = A. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports through-hole mounting in a 14-pin PDIP package. Key electrical characteristics include a maximum propagation delay of 20 ns at 5 V with 50 pF load, output drive currents of ±4 mA, and a maximum quiescent current of 2 µA. It functions across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Contains six independent inverters for signal inversion
• CMOS technology ensures low power consumption
• Compatible with standard TTL logic levels

Applications

• General-purpose digital logic signal inversion
• Clock signal generation and conditioning
• Combinational logic circuit implementation

Procurement Notes

Verify the specific ordering suffix matches the required package type, as variations exist between plastic DIP and surface-mount options. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as these details are subject to change based on manufacturing schedules and regional availability.

Selection Notes

Select this component when a wide operating voltage range (2V to 6V) and low static power consumption are required. It serves as a direct replacement for older 74LS series inverters where lower power dissipation is prioritized over speed. Ensure the application does not require Schmitt trigger inputs or higher drive capabilities than the standard CMOS outputs provide.

Part Context

This part belongs to the widely adopted 74HC series of high-speed CMOS logic devices. It is designed to be pin-compatible with legacy 74LS logic families while offering improved power efficiency and broader voltage tolerance. The SN74HC04N specifically provides the inverter function necessary for basic digital logic operations in mixed-technology systems.

Replacement Considerations

SN74HC04NE4 is a verified equivalent variant from Texas Instruments.
