SN74HCS04DR

Inverter Gates Overview

The SN74HCS04DR is a hex inverter with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an extended ambient temperature range from -40°C to +125°C. The device features balanced CMOS push-pull outputs capable of ±7.8 mA drive current at 6 V. Key electrical characteristics include a typical propagation delay of 5 ns at 6 V, low power consumption with a typical supply current of 100 nA, and high noise immunity provided by Schmitt-trigger hysteresis.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide tolerance for slow or noisy input signals
• Balanced CMOS push-pull outputs support significant output drive currents
• Low power consumption design minimizes static current draw

Inverter Gates Applications

• Synchronizing inverted clock inputs
• Switch debounce circuits
• Digital signal inversion

Inverter Gates Procurement Notes

Verify the specific package type (SOIC-14) matches the target PCB footprint. Confirm that the operating environment remains within the specified -40°C to +125°C temperature range. Ensure supply voltage stays between 2 V and 6 V. Check for RoHS compliance requirements if applicable to the assembly process.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger architecture. It is suitable for applications requiring signal inversion where input signals may have slow transition times. Consider the extended temperature range for harsh environments. Verify that the required output drive current does not exceed the specified limits.

Inverter Gates Part Context

This device belongs to the SNx4HCSxx logic family, which integrates Schmitt-trigger functionality into standard CMOS logic gates. The 'D' suffix indicates the SOIC surface-mount package. It serves as a digital logic component designed for robust signal processing in industrial and consumer electronics.

Inverter Gates Replacement Considerations

SN74HC04DR: Standard HC series without Schmitt triggers. SN74HCT04DR: HCT series with TTL-compatible input levels. SN74LVC1G04: Single gate alternative.
