SN74HCS05DR

Inverter Gates Overview

The SN74HCS05DR is a hex inverter integrated circuit from Texas Instruments, belonging to the SN74HCS logic family. It features six independent inverters with open-drain outputs housed in a 14-pin SOIC package. The device operates within a wide supply voltage range of 2 V to 6 V and supports Schmitt-trigger inputs for noise immunity. Key electrical parameters include a maximum propagation delay of 15 ns at 6 V with 50 pF load, low-level output current of 7.8 mA, and high-level output current of -7.8 mA. It functions reliably across an extended temperature range from -40°C to +125°C.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide enhanced noise filtering and tolerance for slow or noisy input signals
• Open-drain output configuration allows for flexible interfacing with various logic families and voltage levels
• Low power consumption characteristics suitable for energy-efficient designs

Inverter Gates Applications

• Signal conditioning for noisy digital environments
• Level shifting between different voltage domains
• General-purpose inversion in microcontroller interfaces

Inverter Gates Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-14 package and tape-and-reel packaging format as documented in the official datasheet. Confirm RoHS compliance status through the manufacturer's latest environmental documentation. Ensure the operating temperature range meets your application requirements before finalizing procurement decisions.

Inverter Gates Selection Notes

Select this component when open-drain outputs are required for wired-AND configurations or voltage translation. The Schmitt-trigger input feature makes it suitable for applications involving signal degradation or slow rise times. Compare against standard CMOS alternatives if higher drive current or push-pull outputs are needed instead.

Inverter Gates Part Context

This part belongs to the SN74HCS series, which combines high-speed CMOS technology with Schmitt-trigger inputs. It serves as a specialized variant within the broader 74xx logic family, designed specifically for robust performance in electrically noisy industrial and commercial environments while maintaining low power dissipation.

Inverter Gates Replacement Considerations

Direct pin-compatible substitutes may include other SN74HCS05 variants with different packaging options such as TSSOP. Verify that any replacement maintains the open-drain output characteristic and Schmitt-trigger input specifications to ensure functional equivalence in existing designs.
