SN74HCS365QWBQBRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCS365QWBQBRQ1 is an automotive-grade hex buffer and line driver featuring Schmitt-trigger inputs and three-state outputs. It operates within a supply voltage range of 2 V to 6 V, with a typical operating voltage of 5 V. The device provides balanced push-pull outputs capable of sourcing and sinking up to 7.8 mA at 6 V. Propagation delay ranges from 4 ns to 32 ns depending on the supply voltage and temperature conditions. It includes dual output enable pins for independent channel control.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• AEC-Q100 qualified for automotive applications with extended temperature support
• Schmitt-trigger inputs provide high tolerance for slow or noisy signals
• Wettable flank QFN package enables reliable soldering and automatic optical inspection
• Low power consumption with minimal static current draw

Buffers, Drivers, Receivers, Transceivers Applications

• Enable or disable digital signals in bus-oriented systems
• Eliminate slow or noisy input signals through hysteresis filtering
• Hold signals stable during controller reset sequences
• Debounce mechanical switches for reliable logic transitions

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific WBQB package suffix matches the required wettable flank configuration. Confirm AEC-Q100 qualification grade aligns with automotive system requirements. Check recommended operating conditions against target supply voltages. Ensure thermal management meets junction temperature limits under maximum load.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving long traces or transmission lines requiring signal integrity maintenance. Choose for environments with significant electrical noise due to Schmitt-trigger architecture. Opt for the WBQB package when board space is limited and enhanced solder joint reliability is critical. Consider parallel channel usage if higher drive strength is needed beyond single-channel capabilities.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HCS365-Q1 family of automotive hex buffers. It shares functional characteristics with other HCS series devices but is distinguished by its specific WBQB packaging and automotive qualification. It serves as a robust interface solution for automotive electronic control units and peripheral communication buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other SN74HCS365-Q1 variants with different packages such as SN74HCS365D-Q1 (SOIC) or SN74HCS365PW-Q1 (TSSOP). Verify pin compatibility and thermal performance when substituting packages. Non-automotive equivalents like SN74HC365 lack the required qualification and Schmitt-trigger features.
