74LCX14TTR

Inverter Gates Overview

The 74LCX14TTR is a low-voltage CMOS hex Schmitt inverter manufactured using sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a supply voltage range of 2.0 V to 3.6 V, with truth table functionality guaranteed from 1.5 V to 3.6 V. The device features 5 V tolerant inputs capable of interfacing with 5 V signal environments. At VCC = 3 V, it achieves a maximum propagation delay (tPD) of 5.0 ns. Output drive capability is symmetrical, providing a minimum output current (|IOH| = IOL) of 24 mA at VCC = 3 V.

Inverter Gates Feature Summary

• Features Schmitt trigger action with hysteresis for noise immunity on line receivers with slow rise/fall input signals
• Provides power-down protection on all inputs and outputs
• Includes protection circuits against static discharge and transient excess voltage

Inverter Gates Applications

• Low-power and high-speed 3.3 V applications
• Line receivers requiring slow rise/fall input signal processing
• Systems interfacing 3.3 V logic to 5 V signal environments

Inverter Gates Procurement Notes

Verify the specific package type matches the required design constraints, as the 74LCX14 series is available in both SO-14 and TSSOP14 configurations. Confirm that the ordering suffix corresponds to the tape and reel packaging format intended for automated assembly processes. Ensure compatibility with the target operating temperature range and verify that the component meets the necessary environmental standards for the final product application.

Inverter Gates Selection Notes

Select this component when hysteresis is required to stabilize noisy or slowly changing input signals compared to standard inverters. It serves as a direct pin-compatible replacement for the 74LCX04 while adding Schmitt trigger functionality. Consider its 5 V tolerance for mixed-voltage systems where inputs may exceed the core supply voltage. Evaluate the 24 mA output drive capability against load requirements to ensure signal integrity across the bus.

Inverter Gates Part Context

This device belongs to the 74LCX family of low-voltage CMOS logic components. It shares the same pin configuration and function as the 74LCX04 but incorporates internal hysteresis typical of the 74 series 14 logic family. The technology combines the speed performance of the 5 V AC/ACT family with lower power consumption, making it suitable for portable and battery-operated equipment.

Inverter Gates Replacement Considerations

The 74LCX14 is pin and function compatible with other 74 series 14 devices. Verify that substitute parts support the required 5 V input tolerance and the specific operating voltage range of 2.0 V to 3.6 V.
