74AHCT1G14DCKTE4

Overview

The SN74AHCT1G14DCKTE4 is a single Schmitt-trigger inverter from Texas Instruments' AHCT logic family, housed in a SC-70-5 surface-mount package. It operates within a supply voltage range of 2 V to 5.5 V and supports TTL-compatible input thresholds. The device features low static power consumption and offers robust noise immunity through its Schmitt-trigger action. It is designed for high-speed digital applications requiring signal conditioning and waveform shaping across industrial temperature ranges.

Feature Summary

• Schmitt-trigger action provides hysteresis for improved noise immunity and clean signal transitions
• TTL-compatible input thresholds allow direct interfacing with legacy TTL logic systems
• Single-channel inverter configuration minimizes board space requirements

Applications

• Signal conditioning for noisy digital environments
• Waveform shaping and pulse generation circuits
• Interfacing between CMOS and TTL logic domains

Procurement Notes

Verify the complete part number including the E4 suffix to ensure compliance with specific environmental standards. Confirm the SC-70-5 package type matches your PCB footprint design. Check datasheet specifications for operating temperature ranges and electrical characteristics relevant to your application before procurement.

Selection Notes

Select this component when TTL-compatible inputs are required alongside Schmitt-trigger noise immunity. Compare propagation delay and output drive capabilities against standard AHC or LVC variants if speed or current requirements differ. Ensure the 5.5 V maximum rating aligns with your system's supply voltage constraints.

Part Context

This component belongs to the SN74AHCT1Gxx series of single-function gates. It shares the SC-70-5 package form factor with other devices in the family but differs in logical function and input threshold compatibility. The AHCT series specifically bridges the gap between modern CMOS technology and traditional TTL logic levels.
