SN74HCT14DG4 Hex Schmitt-Trigger Inverters by Texas Instruments

The SN74HCT14DG4 from Texas Instruments is a high-performance, hex inverter circuit that features Schmitt-trigger inputs. Designed for 4.5-V to 5.5-V VCC operation, this device is particularly suitable for implementing buffer circuits with its ability to transform slowly changing input signals into sharply defined, jitter-free output signals, enhancing the noise immunity and transforming an irregular input waveform to a square wave output.

Each inverter in the SN74HCT14DG4 device performs the Boolean function Y = A̅ in positive logic. The Schmitt-trigger action at the input makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 4.5V to 5.5V.

The device functions as six independent inverters and features a wide operating temperature range of -40°C to 85°C, making it suitable for a variety of industrial applications. The inputs are capable of accepting TTL logic levels which make the device compatible with a multitude of digital circuits.

Key Features:

• Operates from 4.5 V to 5.5 V
• Provides down translation to VCC
• Maximum tpd of 14 ns at 5 V
• Typical VOLP (Output Ground Bounce) < 0.8 V at VCC = 5 V, TA = 25°C
• Typical VOHV (Output VOH Undershoot) > 2 V at VCC = 5 V, TA = 25°C
• Supports TTL-level inputs
