SN74HCS08QBQARQ1

Inverter Gates Overview

The SN74HCS08QBQARQ1 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 capable of ±7.8 mA drive current 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 or noisy input signals.
• Balanced CMOS push-pull outputs deliver symmetric sourcing and sinking capabilities.
• Low power consumption design minimizes static current draw during operation.

Inverter Gates Applications

• Combining multiple power good signals into a single logic state.
• Aggregating enable signals for system control logic.
• Directly controlling reset pins in motor controllers requiring multi-signal validation.

Inverter Gates Procurement Notes

Verify the specific BQA package variant matches the required footprint. Confirm AEC-Q100 qualification aligns with target automotive reliability standards. Ensure operating conditions remain within the specified 2 V to 6 V voltage and -40°C to +125°C temperature limits for guaranteed performance.

Inverter Gates Selection Notes

Select this component when designing systems requiring robust noise rejection for slow-rising signals. The Schmitt-trigger architecture eliminates the need for strict input transition rate requirements found in standard CMOS devices. Suitable for applications needing low static power consumption alongside moderate output drive strength.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating. They should be terminated to either VCC or ground using pull-up or pull-down resistors to prevent undefined operational states.

What is the maximum capacitive load recommended?

The device can drive a load with total capacitance less than or equal to 50 pF while meeting all datasheet specifications.
