Overview
The Nexperia 74HC3G14DC-Q100H is a triple inverting Schmitt trigger integrated circuit designed for automotive applications. It features Schmitt-trigger inputs that transform slowly changing signals into sharply defined outputs. The device operates within a supply voltage range of 2.0 V to 6.0 V and includes input clamp diodes, allowing interface to voltages exceeding VCC using current limiting resistors. Qualified to AEC-Q100 Grade 1 standards, it supports ambient temperatures from -40 °C to +125 °C.
Feature Summary
- Triple inverting Schmitt trigger configuration with hysteresis
- Automotive qualification compliant with AEC-Q100 Grade 1
- Wide supply voltage operation from 2.0 V to 6.0 V
- Input clamp diodes enable high-voltage interfacing
Applications
- Wave and pulse shaping in noisy environments
- Astable multivibrators
- Monostable multivibrators
Procurement Notes
Verify the specific suffix 'DC' corresponds to the VSSOP8 package (SOT765-1) required for your layout. Confirm the 'Q100' designation ensures compliance with AEC-Q100 Grade 1 automotive reliability standards. Check the most recent datasheet revision for any updates to power dissipation derating curves or ESD specifications before finalizing design integration.
Selection Notes
Select this component when noise immunity is critical due to its Schmitt-trigger action on all three inverters. It is suitable for mixed-signal environments where inputs may exceed the supply rail, provided current limiting resistors are used. Ensure the operating temperature range meets the -40 °C to +125 °C requirement for harsh automotive conditions.
Part Context
This part belongs to the 74HC3G14-Q100 family of triple inverters. The 'DC' suffix specifically denotes the VSSOP8 plastic very thin shrink small outline package (SOT765-1). It is distinct from the DP variant which uses a TSSOP8 package. The device is part of Nexperia's automotive logic portfolio.
Replacement Considerations
Direct functional equivalents include the 74HC3G14DP-Q100H, which shares identical electrical characteristics but utilizes a TSSOP8 package instead of VSSOP8. Verify pinout compatibility and thermal performance differences between SOT765-1 and SOT505-2 packages during substitution.
