SN74HC04DR

Overview

The SN74HC04DR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74HC series of CMOS logic devices. It contains six independent inverters within a single package. The device operates with a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40 °C to +85 °C. Key electrical parameters include a propagation delay of 20 ns and output drive currents of ±4 mA. It is housed in a 14-pin SOIC surface-mount package.

Feature Summary

• Contains six independent inverter circuits for signal inversion applications
• CMOS technology ensures low power consumption and high noise immunity
• Compatible with standard TTL logic input levels at specified voltages

Applications

• General-purpose digital signal inversion
• Clock signal generation and shaping
• Logic level translation between compatible families

Procurement Notes

Verify the specific ordering suffix DR against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 14-SOIC form factor. Confirm RoHS compliance status as required by project regulations before finalizing procurement orders.

Selection Notes

Select this component when six independent inverters are required in a surface-mount design. The HC series offers a balance of speed and power efficiency suitable for general digital logic. Verify that the 2 V to 6 V supply range aligns with the system power architecture and that the SOIC-14 package fits the assembly constraints.

Part Context
