Overview
The SN74AHCT14NSR is a hex inverter integrated circuit manufactured by Texas Instruments. It belongs to the 74AHCT logic family, utilizing CMOS technology with TTL-compatible inputs. The device contains six independent Schmitt-trigger inverters designed for signal conditioning and waveform shaping. It operates within a supply voltage range of 4.5 V to 5.5 V. The component is housed in a 14-pin TSSOP package and supports surface-mount installation. It features low static power consumption and provides defined output drive capabilities suitable for digital logic applications.
Feature Summary
- Integrates six independent Schmitt-trigger inverters for noise-immune signal processing
- Ensures TTL compatibility through specific input threshold voltage levels
- Provides high-speed operation characteristics typical of the AHCT logic family
Applications
- Signal conditioning for noisy digital environments
- Waveform shaping and pulse generation circuits
- Oscillator circuits requiring hysteresis stability
Procurement Notes
Verify the exact suffix 'SR' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and moisture sensitivity class. Ensure the ordering part number matches the required package variant and temperature grade before procurement. Cross-reference the datasheet revision date to confirm current electrical parameters and pinout configurations.
Selection Notes
Select this component when six independent inverters with Schmitt-trigger action are required in a compact surface-mount package. The AHCT series is appropriate for systems interfacing between 3.3V or 5V CMOS logic and TTL-level signals. Consider the thermal performance and board space constraints associated with the TSSOP-14 footprint during layout planning.
Part Context
This device is part of the broader 74AHCT14 family of hex inverters offered by Texas Instruments. Variants within this family differ primarily in packaging options, such as SOIC, DGV, or QFN, and manufacturing revisions. The SN74AHCT14NSR specifically denotes the TSSOP package configuration intended for automated surface-mount assembly processes.
Replacement Considerations
Compatible substitutes include other 74AHCT14 variants from Texas Instruments with different packages, such as SN74AHCT14DR (SOIC) or SN74AHCT14DGVR (TVSOP). Verify that alternative components maintain the same 14-pin TSSOP footprint and electrical characteristics if direct pin-to-pin replacement is required.
