SN74HCS04QBQARQ1

Inverter Gates Overview

The SN74HCS04QBQARQ1 is an automotive-grade hex inverter featuring Schmitt-trigger inputs, manufactured by Texas Instruments. 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 utilizes a WQFN-14 package and provides balanced push-pull outputs capable of ±7.8 mA drive current at 6 V. Propagation delay ranges from 5 ns to 40 ns depending on the supply voltage. It includes typical supply current of 100 nA and meets AEC-Q100 Grade 1 qualification standards.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow or noisy input signals.
• Balanced CMOS push-pull outputs ensure similar sourcing and sinking capabilities for clean signal transitions.
• Low power consumption design with minimal static supply current suitable for battery-operated applications.
• Automotive qualification ensures reliability under harsh environmental conditions and extended temperature ranges.

Inverter Gates Applications

• Synchronizing inverted clock inputs
• Switch debounce circuits

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package type and reel quantity. Confirm RoHS compliance and lead finish specifications align with assembly requirements. Ensure the component status is listed as active production before finalizing procurement plans. Cross-reference the manufacturer part number with distributor catalogs to validate authenticity and availability.

Inverter Gates Selection Notes

Select this component when designing automotive logic circuits requiring noise rejection for slow-rising signals. The wide voltage range allows compatibility with various power domains. Consider the thermal resistance characteristics if operating near maximum junction temperatures. Verify that the output drive capability meets the load requirements without exceeding absolute maximum ratings.

Inverter Gates Part Context

This device belongs to the SN74HCS04-Q1 family of automotive hex inverters. It shares functional similarities with other HCS series logic devices but is optimized for low power and robust noise performance. The BQA package variant offers a compact footprint compared to traditional SOIC or TSSOP options, facilitating dense PCB layouts in space-constrained automotive modules.

Inverter Gates Replacement Considerations

Direct substitutes include SN74HCS04QDRQ1 (SOIC-14) and SN74HCS04QPWRQ1 (TSSOP-14). These alternatives share identical electrical characteristics and functionality but differ in physical package dimensions and pinout geometry. Ensure mechanical clearance and soldering profiles are compatible with the replacement package type.
