Overview
The SN74AHCT14N is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It belongs to the 74AHCT logic series, utilizing CMOS technology with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting in a PDIP-14 package. It features six independent inverters, each equipped with Schmitt-trigger action for noise immunity. The component functions across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates six independent Schmitt-trigger inverters for signal conditioning
- Provides TTL-compatible input levels while maintaining CMOS output characteristics
- Ensures noise immunity through defined hysteresis voltage thresholds
Applications
- Signal wave shaping and conversion
- Noise filtering in digital circuits
- Pulse generation applications
Procurement Notes
Verify the specific suffix 'N' confirms the PDIP-14 through-hole package variant. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or electrical specification mismatches during integration.
Selection Notes
Select this component when TTL-level compatibility is required alongside CMOS performance benefits. The AHCT series bridges the gap between older TTL systems and modern CMOS designs. Verify that the 4.5V to 5.5V supply range aligns with the system power architecture before implementation.
Part Context
This device is part of the broader 74AHCT family of high-speed CMOS logic devices. It shares functional similarities with other hex inverters but distinguishes itself through integrated Schmitt-trigger inputs. The N suffix specifically denotes the plastic dual-in-line package format suitable for prototyping and through-hole PCB designs.

FAQ
What is the primary function of the Schmitt-trigger feature in this IC?
The Schmitt-trigger action provides hysteresis, which filters out noise on input signals and ensures clean transitions between logic states.
Does this component support 3.3V logic levels?
No, the SN74AHCT14N requires a supply voltage between 4.5V and 5.5V and is designed for TTL-compatible input levels typically associated with 5V systems.
