74HCT2G14GW-Q100H

Overview

The Nexperia 74HCT2G14GW-Q100H is a dual inverting Schmitt trigger IC 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, balanced propagation delays, and high noise immunity. It is housed in a TSSOP6 plastic thin shrink small outline package (SOT363-2) with six leads.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1
• Schmitt trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• Inputs include clamp diodes enabling interface to voltages exceeding VCC via current limiting resistors
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Applications

• Wave and pulse shaper for highly noisy environments
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific suffix 'GW' corresponds to the TSSOP6 (SOT363-2) package variant when sourcing. Confirm that the H-suffix aligns with the required manufacturing or environmental specifications. Ensure compatibility with the 4.5 V to 5.5 V operating voltage range for the HCT logic family. Cross-reference the AEC-Q100 Grade 1 qualification status against project requirements.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside Schmitt trigger hysteresis for signal conditioning. The dual-channel configuration allows for compact designs in space-constrained automotive electronics. Verify that the 5.5 V maximum supply voltage meets system power rail constraints. Consider the thermal derating characteristics if operating near the upper temperature limit.

Part Context

This part belongs to the Nexperia 74HCT2G14-Q100 series, which includes HC and HCT variants. The HCT version specifically provides TTL-level input compatibility, distinguishing it from the CMOS-level HC counterpart. Both share the same automotive qualification and physical package dimensions, ensuring interchangeability in layout while differing in electrical threshold characteristics.

Replacement Considerations

The 74HC2G14GW-Q100H serves as a direct pin-compatible alternative within the same series, offering CMOS-level input thresholds instead of TTL levels.
