Overview
The SN74ACT14PW is a hex inverter from Texas Instruments belonging to the 74ACT logic family. It features TTL-compatible Schmitt trigger inputs designed to handle slow and noisy signals. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides continuous output drive currents of ±24 mA at 5 V, with short-term capabilities reaching ±75 mA. The component is housed in a TSSOP-14 package and supports surface mount installation.
Feature Summary
- TTL-compatible Schmitt trigger inputs for noise immunity
- High output drive capability supporting transmission lines
- Wide operating temperature range availability
Applications
- Digital signal inversion
- Switch debouncing
- Synchronous inverted clock input conditioning
Procurement Notes
Verify the specific suffix against official documentation to confirm exact package type and temperature grade. Ensure the ordering part number matches the required industrial or automotive specifications. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement decisions.
Selection Notes
Select this component when interfacing with TTL logic levels while requiring hysteresis for signal integrity. The ACT series offers faster propagation delays compared to standard AC counterparts. Verify that the system power supply remains strictly within the 4.5 V to 5.5 V operational window to ensure correct logic thresholds and drive performance.
Part Context
This device is part of the broader 74ACT logic family, which bridges the performance gap between older bipolar technologies and modern CMOS solutions. It serves as a direct replacement for legacy 74HCT inverters in designs requiring improved speed and lower power consumption without sacrificing TTL input compatibility.

FAQ
What is the primary function of the Schmitt trigger inputs?
They convert slowly changing or noisy analog-like signals into clean digital pulses by providing distinct threshold voltages for rising and falling edges.
Can this device drive transmission lines directly?
Yes, the high output drive current allows it to drive 50-ohm transmission lines effectively.
