Overview
The SN74AHCT14PWR is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a load capacitance of 50 pF. The device features six independent inverters with TTL-compatible input levels and CMOS output levels. Key electrical parameters include a maximum propagation delay of 12 ns, high-level output current of -8 mA, and low-level output current of 8 mA. It functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates six independent Schmitt-trigger inverters for signal conditioning
- Provides TTL-compatible input thresholds for direct interface with logic families
- Delivers robust CMOS output drive capabilities
- Ensures noise immunity through defined hysteresis characteristics
Applications
- Signal wave shaping and pulse generation
- Oscillator circuits requiring stable switching thresholds
- Level translation between TTL inputs and CMOS outputs
- Debouncing mechanical switches in digital systems
Procurement Notes
Verify the specific ordering suffix PWR confirms the TSSOP-14 package and reel packaging configuration. Confirm RoHS compliance status and manufacturing date codes against current production notices. Ensure the component matches the SN74AHCT14 series specifications rather than similar variants like SN74AHC14 or SN74HCT14 which differ in speed or voltage ranges.
Selection Notes
Select this component when TTL input compatibility is required alongside CMOS output performance. The AHCT series offers faster propagation delays compared to standard HCT devices while maintaining identical pinouts. Verify that the 4.5 V minimum supply voltage aligns with the system power rails. Consider the TSSOP-14 package constraints for thermal management and PCB layout requirements.
Part Context
This part belongs to the SNx4AHCT14 family of hex Schmitt-trigger inverters. It is designed for applications requiring noise filtering and waveform regeneration. The device complements other logic families by bridging TTL and CMOS technologies. It is widely used in industrial and consumer electronics where reliable digital signal processing is essential.
