SN74HCS00DYYR

Inverter Gates Overview

The SN74HCS00DYYR is a quadruple 2-input NAND gate with Schmitt-trigger inputs in a 14-pin SOT-23 package. It operates from 2V to 6V, supporting extended temperatures of -40°C to +125°C. Key electrical parameters include ±7.8mA output drive at 5V, typical supply current of 100nA, and propagation delays ranging from 5ns to 36ns depending on voltage. Input capacitance is 5pF, and power dissipation capacitance per gate is 10pF.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for noise rejection and tolerance to slow input signals
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents
• Low power consumption with minimal quiescent current draw
• Extended ambient temperature range suitable for harsh environments

Inverter Gates Applications

• Alarm or tamper detect circuits
• S-R latch configurations
• Driving tamper indicator LEDs

Inverter Gates Procurement Notes

Verify the specific DYY (SOT-23) package designation matches the target PCB footprint. Confirm the ordering suffix indicates the standard production variant rather than specialized testing samples. Ensure the supplier provides traceability documentation consistent with Texas Instruments manufacturing standards for this logic family.

Inverter Gates Selection Notes

Select this component when noisy signal environments require Schmitt-trigger hysteresis to prevent false triggering. The wide 2V to 6V supply range offers flexibility for mixed-voltage systems. Consider the SOT-23 package size constraints against available board space and thermal requirements compared to larger SOIC or TSSOP alternatives.

Inverter Gates Part Context

This device belongs to the SN74HCS series, which combines high-speed CMOS performance with Schmitt-trigger input characteristics. It serves as a robust alternative to standard CMOS gates in applications requiring improved noise immunity. The HCS series is designed for general-purpose digital logic applications across industrial and consumer electronics.

Inverter Gates FAQ

How do Schmitt-trigger inputs benefit this NAND gate?

They provide hysteresis that makes the device tolerant to slow or noisy input signals, preventing erratic switching behavior.

What is the recommended handling for unused inputs?

Unused inputs must be terminated to either VCC or ground to prevent undefined operational states caused by floating voltages.
