The TC74SH14FU is a Hex Schmitt-Trigger Inverter from Toshiba. This device features six inverters with Schmitt-trigger action, which provides different input threshold levels for positive-going (VT+) and negative-going (VT-) signals. This characteristic improves noise immunity and allows for reliable operation in noisy environments.

Applications

• Wave shaping
• Pulse shaping
• Line receivers
• Schmitt-trigger oscillators
• Monostable multivibrators
• Astable multivibrators
• Noise suppression

Features

• Schmitt-trigger inputs for improved noise immunity
• Wide operating voltage range: VCC = 2 V to 5.5 V
• Low power dissipation: ICC = 1 μA (max) at VCC = 5.5 V
• High-speed operation: tpd = 6 ns (typ.) at VCC = 5 V
• Output drive capability: 15 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 8 mA (min)

Benefits

• Ensures reliable performance in environments with electrical noise.
• Offers flexibility in various voltage systems.
• Reduces power consumption, especially beneficial for battery-powered devices.
• Enables fast signal processing.
• Provides sufficient drive for interfacing with other digital components.

Additional Details

The TC74SH14FU contains six independent inverters. The Schmitt-trigger inputs provide hysteresis, which helps to prevent oscillations and false triggering caused by slow-changing or noisy input signals. All inputs are protected against static discharge and transient voltage conditions. This part comes in a small outline package for space-saving applications.
