74HCT3G14DC-Q100H

Overview

The Nexperia 74HCT3G14DC-Q100H is a triple inverting Schmitt trigger integrated circuit designed for automotive applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels, clamp diodes on inputs, and high noise immunity. It is housed in an SOT765-1 (VSSOP8) package with eight leads.

Feature Summary

• Triple inverting Schmitt trigger configuration
• Qualified to AEC-Q100 Grade 1 standard
• TTL compatible input levels
• High noise immunity with unlimited rise/fall times

Applications

• Wave and pulse shaping in noisy environments
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific suffix 'Q100H' against the manufacturer's current ordering information to ensure correct packaging and qualification status. Confirm that the VSSOP8 package variant matches the design requirements. Cross-reference the datasheet revision date to ensure compliance with the latest electrical specifications and marking codes.

Selection Notes

Select this component when a triple inverter with Schmitt trigger action is required in space-constrained automotive designs. The HCT logic family ensures compatibility with TTL logic levels while operating at standard CMOS voltages. The wide operating temperature range makes it suitable for harsh automotive environments where thermal stability is critical.

Part Context

This part belongs to the Nexperia 74HCT3G14-Q100 series, which includes both HC and HCT variants. The DC suffix specifically denotes the VSSOP8 plastic very thin shrink small outline package (SOT765-1). This series is part of Nexperia's broader portfolio of AEC-Q100 qualified logic devices intended for automotive electronics.

Replacement Considerations

The 74HC3G14DC-Q100H serves as a functional alternative within the same package, differing primarily in input logic level compatibility (CMOS vs. TTL). Designers must verify input voltage thresholds when substituting between HC and HCT families.
