SN74HCS20PWR

Inverter Gates Overview

The SN74HCS20PWR is a dual 4-input NAND gate with Schmitt-trigger inputs in a TSSOP-14 package. It operates from 2 V to 6 V, supporting an ambient temperature range of -40°C to +125°C. The device features balanced CMOS push-pull outputs capable of ±7.8 mA drive at 5 V. Propagation delay ranges from 7 ns to 56 ns depending on supply voltage. Typical supply current is 100 nA, and input leakage is ±100 nA.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for noise rejection and tolerance to slow signals
• Balanced CMOS push-pull outputs ensure similar sourcing and sinking currents
• Low power consumption with minimal typical supply and input leakage currents

Inverter Gates Applications

• Alarm or tamper detect circuits
• S-R latch configurations

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package type and lead finish. Confirm RoHS compliance status and moisture sensitivity level ratings before integration. Ensure the component meets the extended temperature requirements for the intended operating environment. Cross-reference the manufacturer part number against official documentation to validate authenticity and revision history.

Inverter Gates Selection Notes

Select this component when noisy environments require Schmitt-trigger input stability. The wide voltage range supports various logic levels without translation. Verify output drive capabilities meet load requirements to prevent excessive current draw. Consider thermal resistance values if multiple gates operate simultaneously under heavy loads.

Inverter Gates Part Context

This device belongs to the HCS logic family, designed for low power and high noise immunity. It provides two independent 4-input NAND functions within a single integrated circuit. The TSSOP-14 package offers a compact footprint suitable for surface-mount assembly. It serves as a robust solution for digital logic processing in demanding conditions.

Inverter Gates FAQ

How does the Schmitt-trigger architecture affect input signal handling?

It provides hysteresis that allows the device to tolerate slow or noisy input signals without erratic switching.

What are the limits for unused inputs?

Unused inputs must not be left floating; they should be terminated to either VCC or ground to prevent undefined operational states.
