SN74HCS20QPWRQ1

Inverter Gates Overview

The SN74HCS20QPWRQ1 is an automotive-grade dual 4-input NAND gate with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an 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 5 V. Propagation delay ranges from 7 ns to 56 ns depending on the supply voltage. It is housed in a 14-pin TSSOP package.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for noise rejection and tolerance to slow input signals
• AEC-Q100 qualified for automotive applications ensuring reliability under specified conditions
• Balanced CMOS push-pull outputs allow similar sourcing and sinking 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, as the SN74HCS20-Q1 family includes both SOIC and TSSOP variants. Confirm that the AEC-Q100 qualification aligns with your system's environmental requirements. Ensure unused inputs are terminated properly to prevent undefined states and excessive power consumption during operation.

Inverter Gates Selection Notes

Select this component when designing systems requiring robust noise immunity due to its Schmitt-trigger architecture. It is suitable for applications needing low static power consumption alongside high output drive capabilities. Consider the wide operating voltage range if interfacing with various logic levels within the 2 V to 6 V spectrum.
