Overview
The SN74AC14DBR is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It belongs to the AC logic series and utilizes CMOS technology. The device features six independent inverters with Schmitt-trigger inputs, housed in a 14-pin SSOP package. It operates within a supply voltage range of 2 V to 6 V and supports surface mount installation. The component functions across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates six independent inverting channels within a single integrated circuit package.
- Incorporates Schmitt-trigger input stages to provide defined threshold voltages for noise immunity.
- Utilizes CMOS construction to achieve low static power consumption while maintaining high-speed switching capabilities.
Applications
- Signal conditioning for noisy digital environments requiring hysteresis
- Waveform shaping of slow-rise or slow-fall time signals
- Oscillator circuits utilizing RC timing networks
Procurement Notes
Verify the specific suffix 'DBR' corresponds to the SSOP-14 package and tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 2V to 6V supply voltage range and industrial temperature limits.
Selection Notes
Select this component when six isolated inverting channels are required with Schmitt-trigger functionality. The AC logic family offers higher speed performance compared to standard HC variants. Verify that the SSOP-14 footprint aligns with PCB layout constraints and that the 24mA output drive capability meets load requirements.
Part Context
This part is a member of the SN74AC14 family of hex Schmitt-trigger inverters. It shares functional characteristics with other variants such as SN74AC14DR (SOIC) and SN74AC14PWR (TSSOP), differing primarily in physical package dimensions and mounting style while maintaining identical electrical specifications.

FAQ
What is the primary function of the Schmitt-trigger inputs?
The Schmitt-trigger inputs provide two distinct threshold voltages, which eliminates output oscillation caused by noise on slowly changing input signals.
Does the DBR suffix indicate a different logical function than other SN74AC14 variants?
No, the DBR suffix specifies the SSOP-14 package type and reel packaging; the logical function remains a hex Schmitt-trigger inverter consistent with the rest of the family.
