Overview
The SN74ACT14DBLE is a hex Schmitt-trigger inverter from the Texas Instruments SNx4ACT14 family, housed in a 14-pin SSOP package. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible inputs that accept voltages up to 5.5V. The device provides balanced CMOS push-pull outputs with a maximum propagation delay of 11ns at 5V. It includes positive-going thresholds (VT+) ranging from 1.2V to 2.1V and negative-going thresholds (VT-) from 0.5V to 1.4V, ensuring hysteresis for noise immunity.
Feature Summary
- Schmitt-trigger action enables clean output signals from slow or noisy input ramps
- TTL-voltage compatible inputs allow direct interfacing with standard logic levels
- Balanced CMOS push-pull outputs provide symmetric sourcing and sinking capabilities
Applications
- Synchronizing inverted clock inputs
- Debouncing mechanical switches
- Inverting digital signals
Procurement Notes
Verify the specific 'DBLE' suffix against the latest TI Package Option Addendum to confirm current production status and exact marking codes. Ensure the SSOP-14 footprint matches the provided outline drawing dimensions. Confirm RoHS compliance and lead finish specifications required for your assembly process.
Selection Notes
Select this component when noise immunity is critical due to its Schmitt-trigger input structure. It is suitable for applications requiring signal inversion where input edges may be slow or contaminated with noise. Verify that the operating temperature range meets system requirements and that the 5V supply voltage aligns with the design constraints.
Part Context
This part belongs to the SNx4ACT14 series of hex inverters designed for high-speed CMOS technology. The ACT series offers performance improvements over older AC families while maintaining compatibility. The DBLE designation indicates a specific SSOP package variant intended for surface-mount applications requiring compact board space.

FAQ
How does the Schmitt trigger functionality benefit signal processing?
The Schmitt trigger provides different threshold levels for rising and falling edges, which eliminates output jitter and ringing caused by slow input transitions or electrical noise.
What is the maximum input voltage tolerance?
The inputs are tolerant to 5.5V regardless of the VCC level, allowing for safe voltage translation from 3.3V systems to 5V logic environments.
