SN74LS04DB

Inverter Gates Overview

The SN74LS04DB is a Texas Instruments hex inverter integrated circuit belonging to the 74LS (Low-power Schottky) logic family. It contains six independent inverters housed in a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.75V to 5.25V, with a typical propagation delay of 15ns at 5V and 15pF load. It features a low-level output current drive capability of 8mA and a high-level output current of -400µA. The component supports an operating temperature range from 0°C to 70°C.

Inverter Gates Feature Summary

• Contains six independent inverting gates for signal inversion
• Utilizes Low-power Schottky technology for reduced power consumption
• Provides standard TTL-compatible input and output levels

Inverter Gates Applications

• Digital logic signal inversion
• Clock signal generation circuits
• General-purpose switching applications

Inverter Gates Procurement Notes

Verify the specific suffix 'DB' against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 14-SOIC form factor. Confirm RoHS compliance status as per the latest production data sheet revision before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when a surface-mount hex inverter is required for low-power Schottky logic designs. It serves as a direct functional replacement for through-hole DIP variants like the SN74LS04N where board space is limited. Verify that the 8mA sink current meets the load requirements of the connected downstream logic gates or indicators.

Inverter Gates Part Context

This part belongs to the widely adopted 74LS series, which bridges the performance gap between standard 74TTL and older 74S families by offering comparable speed with significantly lower power dissipation. The SN74LS04 specifically provides the fundamental Boolean NOT function across six channels, making it a staple component in digital system design.

Inverter Gates Replacement Considerations

Compatible substitutes include SN74LS04DR and SN74LS04DRE4 from Texas Instruments. Cross-manufacturer equivalents such as MC74LS04 or HD74LS04P are functionally interchangeable provided pinouts match.
