Overview
The SN74AC14PWR is a hex Schmitt-trigger inverter manufactured by Texas Instruments, belonging to the AC logic series. It features six independent inverters with Schmitt-trigger inputs for noise filtering. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a TSSOP-14 package. It provides push-pull outputs with high drive capability, ensuring robust signal integrity across industrial temperature ranges from -40°C to +85°C.
Feature Summary
- Integrates six independent inverters with Schmitt-trigger input thresholds to filter noisy signals and prevent false triggering.
- Operates over a wide supply voltage range from 2 V to 6 V, compatible with various digital logic families.
- Features CMOS push-pull outputs capable of driving significant loads without external components.
Applications
- Signal conditioning for noisy digital lines
- Waveform shaping and pulse generation
- Oscillator circuits requiring stable switching thresholds
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-14 package and tape-and-reel orientation before ordering. Confirm RoHS compliance status as required by your assembly specifications. Ensure the design accommodates the thermal characteristics of the thin-shrink small-outline package for reliable operation.
Selection Notes
Select this component when noise immunity is critical due to its Schmitt-trigger inputs. It is suitable for applications requiring operation across a broad voltage spectrum including 3.3 V and 5 V systems. Consider the TSSOP-14 footprint constraints and ensure adequate PCB space for the specified package dimensions.
Part Context
This part belongs to the SN74AC14 family of hex inverters. It serves as a standard solution for converting slow or noisy digital signals into clean, sharp transitions. The AC series offers improved speed and power consumption characteristics compared to older HC or HCT counterparts while maintaining pin compatibility.
Replacement Considerations
SN74ACT14PWRG4: ACT series variant with different voltage tolerance limits; verify 5.5 V max rating suitability. SN74AC14DR: Alternative SOIC-14 package version from the same manufacturer; check pin-to-pin mechanical compatibility.
