CD74AC14EE4

Inverter Gates Overview

The CD74AC14EE4 is a hex Schmitt-trigger inverter from the Texas Instruments AC logic family. It operates on a supply voltage range of 1.5V to 5.5V and provides balanced noise immunity at 30% of the supply voltage. The device features ±24mA output drive current, enabling a fanout of up to 15 F-series devices. Propagation delays are balanced, with typical values ranging from 3.8ns to 6.9ns at 5V. It utilizes an SCR latchup-resistant CMOS process and supports operating temperatures from -55°C to +125°C.

Inverter Gates Feature Summary

• Hex Schmitt-trigger inverters provide distinct positive-going and negative-going input threshold levels for enhanced signal conditioning.
• Balanced propagation delays ensure consistent timing performance across transitions.
• High output drive capability allows direct interfacing with heavy loads or transmission lines.
• Robust design includes SCR latchup resistance and wide supply voltage operation.

Inverter Gates Applications

• Signal wave shaping for converting slow-rise-time signals into clean digital pulses
• Noise filtering in environments with significant electrical interference
• Pulse generation circuits requiring precise threshold control

Inverter Gates FAQ

What is the primary function of the Schmitt trigger action in this device?

The Schmitt trigger action creates different input threshold voltages for rising and falling signals, providing hysteresis that prevents output oscillation caused by noisy or slowly changing input signals.

How does the output drive capability compare to standard inverters?

The device provides ±24mA output drive current, which is significantly higher than standard inverters, allowing it to drive up to 15 F-series devices.
