SN74HCS32QBQARQ1

Inverter Gates Overview

The SN74HCS32QBQARQ1 is an automotive-grade quadruple 2-input OR gate featuring 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 provides balanced CMOS push-pull outputs capable of ±7.8 mA drive current at 6 V. It includes low power consumption characteristics with typical ICC of 100 nA and input leakage of ±100 nA. ESD protection meets AEC-Q100 standards, offering HBM Level 2 (±4000 V) and CDM Level C6 (±1500 V).

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow or noisy signal transitions.
• Balanced CMOS push-pull outputs deliver symmetric sourcing and sinking capabilities.
• Low power consumption design minimizes static current draw during operation.

Inverter Gates Applications

• Monitoring error signals using fewer logic inputs
• Combining active-low enable signals
• Direct control of fan driver enable pins

Inverter Gates Procurement Notes

Verify the specific BQA package variant matches the required footprint. Confirm AEC-Q100 qualification aligns with automotive reliability standards. Check RoHS compliance status before integration. Ensure thermal management considerations are addressed for the WQFN-14 package in high-temperature environments.

Inverter Gates Selection Notes

Select this component when wide voltage operation between 2 V and 6 V is required. Choose based on the need for Schmitt-trigger hysteresis to handle noisy automotive environments. Consider the WQFN-14 package for compact board space requirements compared to SOIC or TSSOP alternatives.

Inverter Gates Part Context

This part belongs to the SN74HCS32-Q1 family of automotive quadruple 2-input OR gates. It shares functional similarities with other HCS series devices but is distinguished by its specific BQA WQFN-14 packaging and automotive qualification. It complements other logic families like AHCT for different voltage domains.

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 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.
