74AHC14D-Q100,118

Overview

The Nexperia 74AHC14D-Q100,118 is a hex inverting Schmitt trigger qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, high noise immunity, and CMOS low power dissipation. Propagation delays are specified at 16.0 ns maximum for a 50 pF load at 3.0 V to 3.6 V, and 13.5 ns maximum at 4.5 V to 5.5 V. Latch-up performance exceeds 100 mA per JESD 78 Class II Level A.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Overvoltage tolerant inputs enabling use as translators in mixed voltage environments
• Schmitt-trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• High noise immunity with balanced propagation delays

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74AHC14-Q100 family includes SO14, TSSOP14, and DHVQFN14 options. Confirm that the D suffix corresponds to the SOT108-1 plastic small outline package. Ensure the component meets the required temperature grade and electrical specifications for the target automotive application environment before finalizing procurement.

Selection Notes

Select this component when a hex inverter with Schmitt-trigger functionality is required for automotive systems. It is suitable for translating signals between mixed voltage domains due to its overvoltage tolerant inputs. Consider the SO14 package dimensions and thermal characteristics if space or heat dissipation is a constraint. Verify compatibility with the system's supply voltage range and noise immunity requirements.

Part Context

This part belongs to the Nexperia 74AHC14-Q100 series, which includes variants like the 74AHCT14D-Q100. The series is designed for automotive applications requiring high reliability and robust signal conditioning. The D suffix specifically denotes the SO14 package variant within this broader family of hex inverters.

Replacement Considerations

Direct substitutes include other 74AHC14-Q100 variants with different packages, such as 74AHC14PW-Q100 (TSSOP14) or 74AHC14BQ-Q100 (DHVQFN14). Cross-family replacements require verification of pinout compatibility, electrical parameters, and package dimensions.
