Overview
The SN74AHC1G14DBVT is a single Schmitt-trigger inverter gate from the Texas Instruments SN74AHC1Gxx series. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature range of -40°C to +125°C. The device features a propagation delay of 10.6 ns at 5 V with a 50 pF load, and provides output drive currents of 8 mA for both high and low states. It is housed in a SC-70-5 (SOT-353) surface-mount package.
Feature Summary
- Integrates Schmitt-trigger input functionality to filter noisy signals and provide clean switching transitions.
- Delivers high-speed performance with low propagation delay suitable for general-purpose digital applications.
- Supports wide supply voltage operation from 2 V to 5.5 V for flexible system integration.
Applications
- Signal conditioning for noisy digital lines
- Pulse generation and shaping circuits
- Oscillator clock signal generation
Procurement Notes
Verify the specific suffix 'VT' indicates tape-and-reel packaging when ordering. Confirm the logic family is AHC rather than AHCT to ensure correct voltage compatibility. Check RoHS compliance status against current manufacturing notices. Ensure the SC-70-5 footprint matches the design layout requirements.
Selection Notes
Select this component when a single inverter with hysteresis is required in a minimal footprint. The AHC series offers faster speeds than standard 74HC devices while maintaining CMOS power efficiency. Verify that the 2 V minimum supply voltage meets the lowest system rail requirement.
Part Context
This part belongs to the SN74AHC1Gxx family of ultra-small single-gate logic ICs. It shares functional similarities with the SN74AHC1G04 but adds Schmitt-trigger inputs for improved noise immunity. The DBVT designation specifies the SC-70-5 package and reel packaging format.
Replacement Considerations
SN74AHC1G14DCKR serves as a direct pin-compatible alternative in the same SC-70-5 package. SN74AHC1GU04DBVR is functionally similar but lacks Schmitt-trigger inputs. Verify voltage levels and package orientation before substitution.
