Overview
The SN74AHCT14DRG4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features six independent inverting channels. The device utilizes CMOS logic technology with HCT input compatibility, ensuring standard TTL voltage levels are accepted. It is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with a width of 3.90mm. The component supports surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates six independent Schmitt-trigger inverters for signal conditioning
- Provides noise filtering and waveform shaping through defined hysteresis voltages
- Features HCT-compatible inputs compatible with standard TTL logic levels
Applications
- Signal conditioning for noisy digital environments
- Waveform shaping from slow or distorted input signals
- Threshold detection circuits requiring stable switching points
Procurement Notes
Verify the specific suffix DRG4 to confirm the tape-and-reel packaging format and lead-free composition. Ensure the order matches the exact manufacturer part number to avoid confusion with non-G4 variants that may differ in packaging or environmental compliance status.
Selection Notes
Select this component when six isolated inverting channels with Schmitt-trigger action are required at 5V logic levels. The HCT input interface allows direct interfacing with older TTL-based systems while maintaining CMOS power efficiency. The SOIC-14 package offers a compact footprint suitable for dense board layouts.
Part Context
This part belongs to the SN74AHCT series, which combines advanced high-speed CMOS technology with standard TTL-compatible inputs. The 'A' denotes advanced speed, 'H' indicates CMOS technology, and 'CT' specifies TTL-compatible inputs. The 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing processes.
Replacement Considerations
SN74AHCT14DR is a compatible alternative from Texas Instruments with identical electrical characteristics but potentially different packaging specifications.
