SN74HCS20DR

Inverter Gates Overview

The SN74HCS20 is a 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 56 ns depending on the supply voltage. Input leakage current is typically ±100 nA, and supply current is typically 100 nA.

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 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 package variant required, as the SN74HCS20DR utilizes a 14-pin SOIC housing. Confirm that the operating environment remains within the specified -40°C to +125°C thermal limits. Ensure supply voltages do not exceed the absolute maximum ratings to prevent permanent damage. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Inverter Gates Selection Notes

Select this component when noisy environments require Schmitt-trigger input stability. The wide voltage range accommodates systems operating between 2 V and 6 V. Verify that the output drive capability meets the load requirements without exceeding thermal limits. Consider the extended temperature range suitability for industrial applications compared to standard commercial logic families.
