74HCT1G14GV-Q100H

Overview

The Nexperia 74HCT1G14GV-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 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features TTL-level inputs, clamp diodes, and high noise immunity. It is housed in an SC-74A (SOT753) package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Schmitt-trigger input converts slowly changing signals into sharply defined outputs
• TTL logic level input compatibility
• Integrated input clamp diodes allow interfacing with voltages exceeding VCC

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific suffix GV corresponds to the SOT753 (SC-74A) package configuration. Confirm that the H suffix indicates RoHS compliance status as per the manufacturer's current product data sheet. Ensure the component meets the required AEC-Q100 Grade 1 reliability specifications for the intended automotive application environment.

Selection Notes

Select this component when a single-channel inverter with hysteresis is required for digital signal conditioning. The HCT series ensures compatibility with standard TTL logic levels. Verify that the operating temperature range and supply voltage constraints align with the system design requirements before integration.

Part Context

This part belongs to the Nexperia 74HCT1G14-Q100 family of single inverters. It shares functional characteristics with other members of the series but differs in packaging and specific ordering suffixes. The GV suffix identifies the SC-74A surface-mount package variant.

Replacement Considerations

The 74HC1G14GV-Q100H serves as a CMOS-level alternative within the same package. Cross-reference pinouts and electrical characteristics carefully to ensure compatibility.
