SN74HCS08QDYYRQ1

Inverter Gates Overview

The SN74HCS08QDYYRQ1 is an automotive-grade quadruple 2-input AND gate featuring Schmitt-trigger inputs. It operates within a supply voltage range of 2 V to 6 V and supports ambient temperatures from -40°C to +125°C. The device provides balanced CMOS push-pull outputs with ±7.8 mA drive capability at 6 V. Propagation delay ranges from 6 ns to 36 ns depending on voltage. It includes HBM ESD Level 2 and CDM Level C6 ratings, with typical supply current of 100 nA.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow input signal transitions.
• Balanced CMOS push-pull outputs deliver symmetric sourcing and sinking currents.
• Low power consumption characterized by minimal static supply current and leakage.
• Qualified for automotive applications under AEC-Q100 standards.

Inverter Gates Applications

• Combining multiple power good signals into a single logic state
• Aggregating enable signals for system control
• Directly controlling reset pins in motor controllers

Inverter Gates Procurement Notes

Verify the specific DYY package designation (SOT-23-THIN) matches the target PCB footprint requirements. Confirm that the AEC-Q100 qualification aligns with the specific automotive grade requirements of the end application. Ensure design margins account for the specified thermal resistance values associated with this small outline package type.

Inverter Gates Selection Notes

Select this component when noisy environments require Schmitt-trigger hysteresis to prevent false triggering. Choose this part for designs needing wide voltage flexibility between 2 V and 6 V. Consider the SOT-23-THIN package constraints regarding thermal dissipation and board space limitations compared to larger SOIC or TSSOP alternatives.

Inverter Gates FAQ

How does the Schmitt-trigger architecture affect input handling?

It allows the device to tolerate slow or noisy input signals without causing undefined states or excessive dynamic current consumption.

What are the recommendations for unused inputs?

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