SN74HCS365QPWRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCS365QPWRQ1 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 and supports an ambient temperature range from -40°C to +125°C. 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 voltage and temperature. It includes dual output enable pins for high-impedance control.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt-trigger inputs provide hysteresis to tolerate slow or noisy input signals
• Three-state outputs allow multiple drivers to share bus lines without interference
• Balanced CMOS push-pull architecture ensures similar current sourcing and sinking capabilities
• AEC-Q100 qualified for automotive applications with specified ESD protection levels

Buffers, Drivers, Receivers, Transceivers Applications

• Enable or disable digital signals in automotive systems
• Eliminate slow or noisy input signals through Schmitt-trigger action
• Hold a signal during controller reset sequences
• Debounce mechanical switches
• Drive signals over long traces or transmission lines

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (TSSOP, SOIC, or WQFN) matches the design requirements, as the QPWRQ1 suffix denotes TSSOP. Confirm AEC-Q100 qualification grade 1 compliance for the target operating temperature range. Ensure input and output voltages remain within absolute maximum ratings to prevent damage. Check thermal resistance values if high power dissipation is expected.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger inputs. Use it for bus-oriented receivers or transmitters requiring three-state isolation. Consider the wide operating voltage range for compatibility with various logic families. Verify that the output drive current meets the load requirements without exceeding absolute maximum limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HCS365-Q1 family of automotive hex buffers. It is designed to improve performance and density in memory address drivers and clock drivers. The device integrates six independent buffers with dual-gated output enables. It is manufactured by Texas Instruments for automotive electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Non-automotive equivalents like SN74HC365 lack AEC-Q100 qualification. SN74HCS365PW-Q1 is the same function in TSSOP but without the 'R' suffix indicating reel packaging. SN74HCS365D-Q1 offers the same function in SOIC package. Verify pinout and electrical characteristics match before substitution.
