The MM74LCX14MTCX is a low-voltage hex Schmitt-trigger inverter with 5V tolerant inputs. It is part of the LCX family of logic gates, designed for high-performance, low-power applications. The Schmitt-trigger inputs provide improved noise immunity and allow for the use of slow or noisy input signals.

Applications:

• Wave Shaping
• Noise Suppression
• Pulse Shaping
• Debouncing
• Clock Generation

Features:

• 5V Tolerant Inputs: Allows interfacing to 5V logic
• Low Voltage Operation: VCC = 2.0V to 3.6V
• Schmitt-Trigger Inputs: Provide improved noise immunity
• Ultra-High Speed: tPD = 6.5 ns (typical) at VCC = 3.3V and CL = 50 pF
• Low Power Dissipation: ICC = 10 μA (maximum) at TA = 25°C
• Balanced Propagation Delays: tPLH ≈ tPHL
• Output Drive Capability: IOL/IOH = 24 mA at VCC = 3.0V
• Pin and Function Compatible with 74HC14

Benefits:

• Enables interfacing with both 3.3V and 5V logic systems.
• Improved noise immunity in noisy environments.
• Allows the use of slow or noisy input signals.
• High-speed operation allows for use in demanding applications.
• Reduced power consumption extends battery life.
• Simplified design due to balanced propagation delays.
• High output drive allows for driving heavily loaded buses.

Additional Details:

The MM74LCX14MTCX contains six independent Schmitt-trigger inverters. The Schmitt-trigger action provides different input threshold voltages for rising and falling edges, which reduces the effect of noise on the input signal. The device is available in a TSSOP package.
