Overview
The SN74AHC1G14DBVR is a single Schmitt-trigger inverter gate from Texas Instruments, belonging to the AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and supports an output current of 8 mA for both high and low states. The device features a propagation delay of 10.6 ns at 5 V with a 50 pF load. It is housed in a SOT-23-5 (SC-74A) surface-mount package and functions reliably across an extended temperature range of -40°C to +125°C.
Feature Summary
- Integrates Schmitt-trigger input characteristics to provide noise filtering and hysteresis for clean signal 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 compatibility with various logic families.
Applications
- Signal conditioning for noisy environments requiring hysteresis
- Oscillator circuits utilizing RC or crystal feedback
- Pulse shaping and waveform generation
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOT-23-5 footprint matches the design layout. Check for any recent product change notifications that may affect pinout or electrical specifications.
Selection Notes
Select this component when a single-channel inverter with Schmitt-trigger inputs is required in a minimal footprint. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Consider the 2 V to 5.5 V operating range to ensure compatibility with the target system voltage levels.
Part Context
This part belongs to the SN74AHC1Gxx family of single-function logic gates designed for space-constrained applications. The AHC series represents an advanced High-CMOS technology optimized for high-speed operation. The DBVR variant specifically denotes the SOT-23-5 package configuration used in compact surface-mount designs.
Replacement Considerations
SN74AHC1G14DBVRE4 is an equivalent revision from the same manufacturer. Cross-vendor alternatives include MC74VHC1G14DBVT1G and 74AHCT1G14GV,125, though voltage ranges and logic families differ.
