74HC9114D-Q100J

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74HC9114D-Q100J is a nine-bit inverting buffer with Schmitt trigger inputs and open-drain outputs, designed for automotive applications. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features reduced input thresholds for TTL interfacing and includes clamp diodes on all inputs. It complies with AEC-Q100 Grade 1 standards and JEDEC ESD specifications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt trigger inputs provide jitter-free output signals from slowly changing input waveforms.
• Open-drain outputs allow flexible interfacing and wired-AND configurations.
• Input clamp diodes enable safe connection to voltages exceeding the supply rail using current-limiting resistors.
• Automotive qualification ensures reliability under specified temperature and electrical stress conditions.

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive logic signal conditioning
• TTL-to-CMOS level translation
• Noise-immune digital buffering

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'J' against the manufacturer's latest documentation to confirm reel packaging details. Confirm the active production status directly with Nexperia or authorized distributors, as automotive components may have extended lead times or lifecycle restrictions. Ensure the SO20 package variant matches the design footprint requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when nine independent inverted channels are required with high noise immunity. The open-drain architecture is suitable for driving loads at different voltage levels than the logic supply. Verify that the application does not require push-pull outputs, as this device only provides open-drain functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74HC9114-Q100 family of wide Schmitt trigger buffers. It is distinct from standard 74HC inverters due to its specific nine-bit configuration and automotive-grade qualification. The D package denotes the SO20 plastic small outline form factor used in surface-mount assemblies.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 74HC9114 variants from Nexperia with compatible pinouts and electrical characteristics. Cross-manufacturer equivalents must be verified for identical Schmitt trigger thresholds and open-drain output capabilities.

Buffers, Drivers, Receivers, Transceivers FAQ

Can the inputs handle voltages higher than VCC?

Yes, the inputs include clamp diodes, allowing them to interface with voltages exceeding VCC when used with current-limiting resistors.

What is the output type of this device?

The device features open-drain outputs, which require an external pull-up resistor to function correctly as a logic driver.
