SN74AS04NS

Overview

The SN74AS04NS is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74AS logic series. It contains six independent inverters performing the Boolean function Y = A. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It features a propagation delay of 5ns at 5V with 50pF load and supports output currents of 2mA high and 20mA low. The component is housed in a 14-SOIC surface-mount package and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Contains six independent inverter circuits within a single package
• Utilizes bipolar AS logic technology for high-speed performance
• Designed for standard 5V digital logic applications

Applications

• Signal inversion in digital logic circuits
• Waveform generation and shaping
• Clock signal conditioning

Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's official documentation to confirm the exact package dimensions and tape-and-reel specifications. Ensure the source document explicitly identifies the part as a Texas Instruments product. Confirm that the 74AS logic family designation matches the required speed and power characteristics for the target design.

Selection Notes

Select this component when high-speed switching is required compared to standard 74S or 74LS families. Verify that the 14-SOIC package footprint fits the PCB layout constraints. Ensure the system power supply remains strictly within the 4.5V to 5.5V range to maintain valid logic levels and prevent damage.

Part Context

This part belongs to the 74AS (Advanced Schottky) logic family, known for superior speed-power trade-offs. It serves as a functional equivalent to other hex inverters like the SN74LS04 but offers faster propagation delays. The SOIC-14 package allows for compact surface-mount assembly in modern electronic designs.

Replacement Considerations

Public confirmed substitute part numbers include SN74AS04D and SN74AS04DR from Texas Instruments.
