SN74HC04NSRG4

Overview

The SN74HC04NSRG4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74HC series of high-speed CMOS logic devices. It contains six independent inverters that perform the Boolean function Y=A bar. The device operates within a supply voltage range of 2 V to 6 V and supports an output drive capability of up to ten LSTTL loads. Key electrical parameters include a maximum propagation delay of 20 ns at 6 V with a 50 pF load, a maximum low-level input current of 1 µA, and a maximum quiescent current of 20 µA. It is housed in a 14-pin SOIC package.

Feature Summary

• Contains six independent inverter circuits for signal inversion
• High-speed CMOS technology ensures low power consumption
• Wide operating voltage range from 2 V to 6 V
• Output drive capability compatible with ten LSTTL loads

Applications

• General-purpose digital logic signal inversion
• Clock signal generation and conditioning
• Buffering for digital data lines
• Level shifting between different logic families

Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to confirm the specific tape-and-reel packaging configuration associated with the 'SRG4' designation. Ensure compliance with RoHS directives as indicated by the 'G4' suffix. Cross-reference the manufacturer's datasheet for the most current mechanical dimensions and thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a hex inverter is required in a surface-mount SOIC-14 package. It is suitable for designs needing wide voltage operation and moderate speed performance typical of the HC logic family. Consider alternative packages such as PDIP or TSSOP if through-hole mounting or smaller footprint is preferred, provided the logical function remains identical.

Part Context

This component is part of the broader SN74HC logic family produced by Texas Instruments. The SN74HC series is widely used in consumer electronics, telecommunications, and industrial control systems due to its compatibility with standard TTL levels while offering lower power consumption than older LS logic families. The SN74HC04 specifically provides the essential inversion function needed in complex digital circuits.

Replacement Considerations

Compatible substitutes include SN74HC04DRG4 (SOIC-14), SN74HC04PWRG4 (TSSOP-14), and SN74HC04N (PDIP-14). Verify pinout compatibility and package dimensions before substitution. Other manufacturers may offer equivalent parts under the 74HC04 designation, but electrical parameters should be compared against the TI datasheet.
