SN74HCS20QDRQ1

Inverter Gates Overview

The SN74HCS20QDRQ1 is an automotive-grade dual 4-input NAND gate with Schmitt-trigger inputs. 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 19 ns depending on the supply voltage. It includes low power consumption characteristics, with typical supply current of 100 nA and input leakage current of ±100 nA.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide noise rejection for slow or noisy signals
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents
• AEC-Q100 qualified for automotive applications with specified ESD protection levels

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific package type (SOIC-14) and suffix (QDRQ1) against the official Texas Instruments orderable addendum to ensure correct manufacturing status and material specifications. Confirm that the component meets the required AEC-Q100 qualification standards for the intended automotive environment before finalizing procurement decisions.

Inverter Gates Selection Notes

Select this component when designing systems requiring robust noise immunity due to its Schmitt-trigger architecture. Ensure the application logic utilizes 4-input NAND functions and fits within the 2 V to 6 V supply voltage constraints. Consider the SOIC-14 package dimensions if board space is limited compared to other available packages in the HCS family.

Inverter Gates Part Context

This part belongs to the SN74HCS20-Q1 series, which consists of dual 4-input NAND gates designed for automotive use. It is distinct from standard logic families by offering enhanced noise tolerance through Schmitt triggers while maintaining low power consumption suitable for battery-operated or efficiency-critical vehicle subsystems.

Inverter Gates Replacement Considerations

The SN74HCS20QPWRQ1 serves as a direct functional substitute using a TSSOP-14 package instead of the SOIC-14 form factor. Both parts share identical electrical characteristics and logical functionality within the SN74HCS20-Q1 family.
