74HC1G14GV-Q100H

Overview

The Nexperia 74HC1G14GV-Q100H is a single inverter with Schmitt-trigger input, qualified to AEC-Q100 Grade 1 for automotive use. 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 CMOS low power dissipation, high noise immunity, and unlimited input rise/fall times. Input levels are compatible with CMOS standards. It includes clamp diodes on inputs and meets JEDEC ESD protection standards exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards.
• Schmitt-trigger input transforms slowly changing signals into sharply defined output.
• Wide operating temperature range supporting -40 °C to +125 °C.
• High noise immunity with balanced propagation delays.

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix 'GV' corresponds to the SC-74A package when sourcing. Confirm that the component meets the required AEC-Q100 Grade 1 specifications for your target application environment. Ensure compatibility with the specified 2.0 V to 6.0 V supply voltage range during system design validation.

Selection Notes

Select this component for applications requiring a single-channel inverter with hysteresis in space-constrained designs. The SC-74A package offers a small footprint suitable for surface-mount assembly. Consider the CMOS input level requirements and ensure the logic family matches the system's voltage thresholds.

Part Context

This part belongs to the Nexperia 74HC1G14-Q100 series, which includes variants like the 74HCT1G14-Q100. The 'GV' suffix specifically denotes the SC-74A plastic surface-mounted package with five leads. It is distinct from the GW variant, which utilizes a TSSOP5 package.

Replacement Considerations

The 74HCT1G14GV-Q100H serves as a functional alternative with TTL-compatible input levels. Other members of the 74HC1G14-Q100 family may be considered if package or electrical parameter differences are acceptable.

FAQ

What is the function of the Schmitt trigger input?

The Schmitt trigger input transforms slowly changing input signals into sharply defined, jitter-free output signals.

Does the device support voltages exceeding VCC?

Yes, the inputs include clamp diodes, enabling the use of current-limiting resistors to interface with voltages higher than VCC.
