SN74S04NG4

Inverter Gates Overview

The SN74S04NG4 is a hex inverter integrated circuit from Texas Instruments, belonging to the 74S (Schottky) logic family. It utilizes bipolar technology with Schottky diodes to achieve high-speed switching while managing power dissipation. The device contains six independent inverters within a single package. It operates on a standard 5V supply voltage ranging from 4.75V to 5.25V. Key electrical characteristics include a propagation delay of 5ns and output drive capabilities of -1mA for high-level and 20mA for low-level states. It is housed in a 14-pin PDIP package suitable for through-hole mounting.

Inverter Gates Feature Summary

• Integrates six independent inverter channels for signal inversion within a single component.
• Employs Schottky clamping technology to minimize storage time and enhance switching speed.
• Provides robust low-level output current drive capability for interfacing with various loads.

Inverter Gates Applications

• Digital signal processing circuits requiring fast logical inversion.
• Clock generation and timing signal conditioning systems.
• General-purpose logic interface applications in industrial control equipment.

Inverter Gates Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type matches the required PCB footprint, typically PDIP-14 for this part number. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Inverter Gates Selection Notes

Select this component when high-speed performance is critical compared to standard TTL or LS logic families. Consider the bipolar power consumption profile against CMOS alternatives if power efficiency is a primary constraint. Verify that the 5V logic level compatibility meets the system requirements. Evaluate the thermal dissipation needs given the higher power draw typical of the S series compared to lower-power variants.

Inverter Gates Part Context

This component is part of the broader 74xx series of logic ICs, specifically the 74S sub-family known for its speed. It serves as a fundamental building block in digital electronics, providing the basic NOT gate function. The SN74S04 variant is widely used in legacy and modern mixed-signal systems where Schottky speed benefits are required without the complexity of ECL logic.

Inverter Gates Replacement Considerations

Direct functional substitutes include the SN74S04N for identical specifications in standard packaging. For lead-free compliant versions, the SN74S04NE4 is an equivalent alternative. Designers may also consider the SN74LS04 for lower power consumption at the cost of reduced speed, or the SN74AS04 for enhanced performance metrics.
