74AHC1G14GW-Q100,1

Overview

The Nexperia 74AHC1G14GW-Q100,1 is a single inverter with Schmitt-trigger inputs, part of the AHC logic family. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device is qualified to AEC-Q100 Grade 1 standards for automotive applications, supporting an ambient temperature range from -40 °C to +125 °C. It utilizes a TSSOP5 (SOT353-1) package with five leads. Static characteristics include low input leakage current and CMOS low power dissipation. Dynamic performance specifies propagation delays ranging from approximately 8.6 ns to 16.5 ns depending on load capacitance and voltage.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• Schmitt-trigger inputs transform slowly changing signals into sharply defined outputs
• Overvoltage tolerant inputs enable use as translators in mixed voltage environments
• High noise immunity with symmetrical output impedance

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the GW designation corresponds to the TSSOP5 plastic thin shrink small outline package. Confirm that the AHC logic level (CMOS switching levels) aligns with system requirements, distinct from the AHCT variant which uses TTL levels. Ensure the component meets the specified AEC-Q100 Grade 1 qualification if intended for automotive deployment. Cross-reference the marking code AF with the datasheet to confirm authenticity upon receipt.

Selection Notes

Select this component when a single inverting function with hysteresis is required in space-constrained designs. The TSSOP5 package offers a compact footprint suitable for surface-mount assembly. Consider the AHC series for its wide supply voltage compatibility and high-speed performance compared to standard HC logic. Verify that the input signal characteristics benefit from Schmitt-trigger action to prevent oscillation during transitions. Ensure the operating environment falls within the specified -40 °C to +125 °C temperature range.

Part Context

This device belongs to the Nexperia 74AHC1G14-Q100 series, which includes variants with different packages such as SC-74A (GV) and XSON5 (GZ). The series shares identical electrical specifications but differs in physical dimensions and thermal properties. The Q100 suffix indicates automotive qualification, distinguishing it from non-qualified commercial versions. All variants maintain the same functional behavior and pinout configuration.

Replacement Considerations

Direct substitutes include other 74AHC1G14-Q100 variants from Nexperia with different packages, such as 74AHC1G14GV-Q100 or 74AHC1G14GZ-Q100. Non-Nexperia equivalents must match the AHC logic family, Schmitt-trigger functionality, and AEC-Q100 Grade 1 qualification. Verify pinout compatibility and ensure equivalent propagation delay and power consumption characteristics.

FAQ
