Overview
The SN74AHC1G14DCK3 is a single Schmitt-trigger inverter gate from the Texas Instruments AHC series. It operates within a supply voltage range of 2V to 5.5V and features low static power consumption with a maximum quiescent current of 1µA. The device provides high noise immunity and supports output drive currents of 8mA at both high and low logic levels. It is housed in a compact SC-70-5 (SOT-353) surface-mount package, suitable for space-constrained designs.
Feature Summary
- Integrates Schmitt-trigger input characteristics to eliminate signal ambiguity and ensure clean transitions for noisy or slowly changing waveforms.
- Delivers robust output drive capability with symmetrical high and low state currents to maintain signal integrity across loads.
- Operates reliably across an extended industrial temperature range, ensuring stable performance in demanding environments.
Applications
- Signal conditioning for microcontroller inputs requiring noise rejection
- Waveform shaping for oscillators and clock circuits
- Pulse width modulation signal processing
Procurement Notes
Verify the specific suffix '3' against the manufacturer's official datasheet to confirm it denotes a standard commercial grade variant rather than a specialized automotive or military qualification. Ensure the SC-70-5 footprint matches the target PCB layout constraints before finalizing procurement decisions.
Selection Notes
Select this component when a single inverting function with hysteresis is required in minimal board space. The AHC series offers superior speed compared to legacy HC devices while maintaining CMOS low-power advantages. Confirm that the 2V to 5.5V operating range aligns with the system's available power rails.
Part Context
This part belongs to the SN74AHC1Gxx family of single-function logic gates. These components are designed to replace older generation logic families by offering faster switching speeds and lower power consumption. The DCK package designation specifically identifies the SC-70-5 plastic small outline package used for surface mount applications.
Replacement Considerations
Direct pin-compatible alternatives include the SN74AHC1G14DCKR and SN74AHC1G14DCKT. Verify electrical specifications and package dimensions match exactly before substitution.
