Overview
The 74AC14TTR is a hex Schmitt trigger inverter manufactured by STMicroelectronics. It operates within a supply voltage range of 2V to 6V and features a typical propagation delay of 4.5ns at 5V. The device provides symmetrical output impedance with minimum drive currents of 24mA for both high and low states. It includes protection circuits against static discharge, offering 2kV ESD immunity. The component utilizes sub-micron silicon gate C2MOS technology.
Feature Summary
- Hex Schmitt trigger inverter configuration
- High-speed CMOS logic operation
- Improved latch-up immunity
- ESD protection on all inputs and outputs
Applications
- Line receivers with slow rise/fall input signals
- Transmission line driving applications
- Signal conditioning and waveform shaping
Procurement Notes
Verify the specific ordering suffix 'TTR' corresponds to the TSSOP-14 tape and reel packaging format as defined in the official datasheet. Confirm that the component meets RoHS compliance requirements before procurement. Ensure the design accounts for the absolute maximum ratings to prevent damage during operation or soldering processes.
Selection Notes
Select this component when a hex inverter with hysteresis is required for noise immunity. The AC series offers higher speed compared to standard HC logic families. Verify that the operating voltage range of 2V to 6V aligns with the system power supply. Consider the TSSOP-14 package dimensions for PCB layout constraints.
Part Context
This part belongs to the 74AC logic family, which represents advanced high-speed CMOS technology. It is functionally compatible with the standard 74S14 pinout but utilizes modern fabrication techniques. The device is designed for general-purpose digital applications requiring fast switching speeds and stable logic levels.
Replacement Considerations
Direct replacements include other manufacturers' 74AC14 variants in TSSOP-14 packages. Ensure any substitute maintains the same Schmitt trigger characteristics and voltage operating range. Verify pin compatibility and electrical specifications match the original design requirements.
