Overview
The SN74AHCT14MDREP 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 features six independent inverters with Schmitt-trigger inputs for noise filtering. The device utilizes CMOS logic technology and provides high-level output current of -8 mA and low-level output current of 8 mA. It is housed in a 14-WQFN package (0004NN) designed for surface-mount applications.
Feature Summary
- Hex Schmitt-trigger configuration for signal conditioning
- CMOS logic technology with TTL-compatible inputs
- High noise immunity through input hysteresis
Applications
- Signal conditioning for noisy environments
- Pulse generation circuits
- Oscillator applications
Procurement Notes
Verify the specific suffix MDREP against official Texas Instruments documentation to confirm the WQFN-14 package type and tape-and-reel packaging format. Ensure compatibility with standard surface-mount assembly processes and check for any automotive or industrial qualification requirements if applicable to the design.
Selection Notes
Select this component when hex inversion with Schmitt-trigger action is required in a compact surface-mount footprint. It is suitable for designs needing TTL-compatible inputs with CMOS outputs. Verify that the operating temperature range and power supply specifications align with the system requirements before finalizing the selection.
Part Context
This part belongs to the SN74AHCT14 family of hex Schmitt-trigger inverters from Texas Instruments. It is part of the broader 74AHCT series, which combines the speed of AHCT logic with CMOS output drive capabilities. The family is designed for general-purpose digital applications requiring noise immunity and fast switching speeds.
Replacement Considerations
Direct replacements include other SN74AHCT14 variants with different packages such as SN74AHCT14DR (SOIC) or SN74AHCT14PW (TSSOP). Cross-manufacturer equivalents like NXP's 74AHCT14 may be considered if pinout and electrical characteristics match.
