74HC1G14GW-Q100H

Overview

The Nexperia 74HC1G14GW-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 an ambient temperature range from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and unlimited input rise/fall times. It includes input clamp diodes for interfacing with voltages exceeding VCC. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Schmitt-trigger input transforms slowly changing signals into jitter-free outputs
• Wide supply voltage range supporting 2.0 V to 6.0 V operation
• High noise immunity with balanced propagation delays

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature grade. Confirm that the component meets all relevant automotive reliability requirements for the intended application environment. Cross-reference the marking code HF with the datasheet to validate authenticity and production batch details before integration.

Selection Notes

Select this component when a single-channel inverting function with hysteresis is required in space-constrained designs. The TSSOP-5 package offers a compact footprint suitable for dense PCB layouts. Ensure the input signal characteristics align with the specified CMOS logic levels and that the operating voltage remains within the 2.0 V to 6.0 V range for optimal performance.

Part Context

This part belongs to the 74HC1G14-Q100 family of single inverters with Schmitt-trigger inputs. It is designed for automotive applications requiring robust noise immunity and wide operating temperature ranges. The GW suffix indicates the TSSOP-5 plastic thin shrink small outline package variant, providing a compact surface-mount solution for modern electronic systems.

Replacement Considerations

The 74HCT1G14GW-Q100H serves as a compatible alternative within the same family, offering TTL-compatible input levels instead of CMOS levels while maintaining identical packaging and automotive qualification.
