74AHCT1G14GW-Q100,

Overview

The Nexperia 74AHCT1G14GW-Q100 is a single inverting Schmitt trigger manufactured using high-speed Si-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device includes overvoltage tolerant inputs capable of withstanding up to 5.5 V, allowing use in mixed-voltage environments. Qualified to AEC-Q100 Grade 1 standards, it supports an ambient temperature range from -40 °C to +125 °C. The component utilizes a TSSOP5 plastic package (SOT353-1) with five leads.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Overvoltage tolerant inputs to 5.5 V
• High noise immunity and symmetrical output impedance
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific suffix 'GW' corresponds to the SOT353-1 (TSSOP5) package variant when sourcing. Confirm that the AHCT designation matches system requirements for TTL input levels, as opposed to the AHC series which uses CMOS levels. Ensure the Q100 Grade 1 automotive qualification aligns with target application reliability standards before finalizing procurement.

Selection Notes

Select this component when TTL-compatible logic interfaces are required within automotive or industrial systems operating at 4.5 V to 5.5 V. The Schmitt-trigger input provides necessary hysteresis for signal conditioning applications involving slow-rise signals. Verify that the single-channel configuration meets design constraints compared to multi-gate alternatives.

Part Context

This part belongs to the 74AHC/AHCT1G14-Q100 family of single inverters with Schmitt-trigger inputs. It shares functional similarities with the 74AHC1G14GW-Q100 but differs in input threshold characteristics. The family offers various package options including SC-74A and XSON5, providing flexibility for different PCB layout requirements while maintaining consistent electrical performance profiles.

Replacement Considerations

The 74AHC1G14GW-Q100 serves as a direct pin-compatible alternative if CMOS input levels are acceptable instead of TTL. Other packages in the same logical family include 74AHCT1G14GV-Q100 (SC-74A) and 74AHCT1G14GZ-Q100 (XSON5). Cross-referencing input thresholds and package dimensions is essential for substitution.
