Overview
The SN74AHC1G14DCKR is a single Schmitt-trigger inverter from the Texas Instruments 74AHC series, housed in a 5-pin SC-70 (SOT-353) surface-mount package. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +125°C. Key electrical parameters include a maximum static current of 1µA, output drive currents of ±8mA, and a maximum propagation delay of 10.6ns at 5V with a 50pF load. The device features low-voltage CMOS technology and complies with RoHS3 standards.
Feature Summary
- Integrates Schmitt-trigger input functionality to tolerate slow input rise and fall times
- Provides low-power operation with a maximum static current of 1µA
- Supports wide supply voltage operation ranging from 2V to 5.5V
- Delivers robust output drive capability of ±8mA
Applications
- Signal conditioning for noisy environments requiring noise immunity
- Pulse width modulation signal generation
- Oscillator circuit design
- Timing delay applications
Procurement Notes
Verify the specific ordering suffix 'R' corresponds to tape-and-reel packaging when sourcing. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Ensure the SC-70-5 footprint matches your PCB layout specifications. Check for any recent Product Change Notifications regarding marking or material updates.
Selection Notes
Select this component when a single inverting channel with hysteresis is required in a minimal footprint. The AHC series offers faster switching speeds compared to standard HC logic while maintaining compatibility with 5V systems. Consider the SC-70 package size constraints and thermal performance for high-density designs.
Part Context
This part belongs to the SN74AHC1G14 family of single Schmitt-trigger inverters. The 'DCK' designation indicates the SC-70-5 package type, while the trailing 'R' specifies reel packaging. It is functionally equivalent to other variants like SN74AHC1G14DCK but differs in shipping configuration.
Replacement Considerations
SN74AHC1G14DCK is the same device in cut-tape or tube packaging. SN74AHC1G14DR is the SOIC-8 variant with six channels. SN74LVC1G14DCKRE4 is a similar LVC series inverter with different voltage thresholds.
