Texas Instruments SN74LVC14APWRG4 Hex Schmitt-Trigger Inverter - Detailed Overview
The SN74LVC14APWRG4 from Texas Instruments is a hex inverting Schmitt-trigger integrated circuit in the 74LVC family, designed for high-speed CMOS logic applications. It features six independent inverters with Schmitt-trigger inputs, providing hysteresis for improved noise immunity and signal conditioning. Operating within a 1.65V to 5.5V supply range, it supports low-voltage operation while maintaining compatibility with 3.3V and 5V systems. The device is available in a 14-pin TSSOP (PW) package, making it suitable for space-constrained PCB designs. With a maximum propagation delay of 5.3 ns at 3.3V, it is optimized for high-speed digital systems while consuming minimal power.
SN74LVC14APWRG4 Key Features
The SN74LVC14APWRG4 offers Schmitt-trigger action on all inputs, ensuring clean signal transitions even with slow or noisy input waveforms. It supports wide voltage operation (1.65V–5.5V), making it versatile for mixed-voltage systems. The device has a high output drive capability (±24mA at 3V), enabling direct interfacing with LEDs, relays, and other low-power loads. Additionally, it features partial power-down protection (Ioff circuitry), preventing backflow current when the device is powered off. With low power consumption (typical ICC of 10µA), it is ideal for battery-powered and portable electronics.
SN74LVC14APWRG4 Applications
This IC is widely used in digital signal conditioning, waveform shaping, and noise filtering across various industries. Common applications include:
· Microcontroller & FPGA interfacing (debouncing switches, cleaning up sensor signals)
· Communication systems (signal conditioning in UART, SPI, I2C interfaces)
· Industrial automation (noise filtering in control systems)
· Consumer electronics (keypad debouncing, touch sensor signal processing)
· Automotive electronics (signal integrity in infotainment & control modules)
Selection Advantages
Compared to standard inverters, the SN74LVC14APWRG4 provides superior noise immunity due to Schmitt-trigger inputs, making it ideal for noisy environments. Its wide voltage range allows seamless integration into mixed-voltage designs, reducing the need for level shifters. The high drive strength supports direct connection to various loads, simplifying circuit design. Additionally, its low power consumption and small TSSOP package make it a preferred choice for portable and space-sensitive applications.
