Overview
The SN74AHCT14PWRE4 is a hex Schmitt-trigger inverter from the Texas Instruments AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels with CMOS output characteristics. The device contains six independent inverters, each equipped with Schmitt-trigger inputs for noise immunity. It is housed in a 14-pin TSSOP package and supports surface-mount installation. The component is designed for operation across an extended temperature range from -40°C to +85°C.
Feature Summary
- Hex configuration providing six independent signal inversion channels within a single integrated circuit.
- Schmitt-trigger input architecture ensures clean signal transitions and enhanced noise rejection capabilities.
- TTL-compatible input thresholds allow direct interfacing with standard digital logic systems.
- CMOS output structure delivers defined high and low logic states suitable for driving subsequent stages.
Applications
- Signal conditioning for noisy digital environments requiring hysteresis
- Waveform shaping of slow-rise or slow-fall time signals
- Threshold detection circuits utilizing defined switching points
Procurement Notes
Verify the E4 suffix indicates lead-free construction and RoHS compliance when sourcing. Confirm the TSSOP-14 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the specific environmental requirements of the application design.
Selection Notes
Select this component when TTL-level compatibility is required alongside Schmitt-trigger noise immunity. The AHCT series bridges the gap between older TTL standards and modern CMOS performance. Verify that the 4.5 V to 5.5 V supply range aligns with the system power rails before integration.
Part Context
This part belongs to the SNx4AHCT14 family of hex inverters manufactured by Texas Instruments. The 'E4' designation typically signifies lead-free packaging and compliance with specific environmental directives. It serves as a specialized variant within the broader AHCT logic portfolio, focusing on robust signal integrity.
Replacement Considerations
Direct pin-to-pin replacements include the SN74AHCT14PWR and SN74AHCT14PW. Verify that substitute parts maintain identical electrical characteristics and package specifications to ensure seamless integration without redesign.
