ON Semiconductor MC74LCX14DTR2G

The MC74LCX14DTR2G by ON Semiconductor is a robust and versatile integrated circuit, specifically designed for applications requiring high-speed and low-power Schmitt trigger inverter functions. This device is part of the LCX family, which is well-known for its 5V tolerant inputs, making it suitable for interfacing with 5V systems while operating at a lower voltage, thus reducing power consumption. This feature ensures compatibility with older logic systems while providing the benefits of modern low-voltage operation.

Constructed using advanced silicon gate CMOS technology, the MC74LCX14DTR2G provides significant improvements over standard CMOS inverters. It includes six Schmitt trigger inverters in a single package, each capable of transforming noisy or slow input signals into sharply defined output signals, thanks to its hysteresis characteristics. This makes it an ideal choice for applications that require signal conditioning, such as transforming an analog signal into a digital one, or for use in environments with high electrical noise.

The device operates over a broad voltage range of 2.0V to 3.6V and features a 5V tolerant input, which can be driven from either 3.3V or 5V devices. This wide range of operation voltages, combined with a low static power consumption of less than 1µA, makes it extremely power-efficient and suitable for battery-operated devices.

The MC74LCX14DTR2G comes in a TSSOP-14 package, which is a space-saving option for PCB designs where board real estate is at a premium. Its performance is guaranteed over the full temperature range of -40°C to +85°C, ensuring reliability in a variety of operating conditions.

Key features of the MC74LCX14DTR2G include:

• High-speed operation: tPD 4.5 ns (max) at VCC = 3.3V
• Power-off disable outputs permit "live insertion"
• Typical VOLP (Output Ground Bounce) < 0.8V at VCC = 3.3V, TA = 25°C
• Support for LVTTL and LVCMOS
• Multiple package options for design flexibility

Whether it's for signal conditioning, pulse shaping, or interfacing with different logic levels, the MC74LCX14DTR2G from ON Semiconductor is a reliable and efficient solution that meets the needs of a wide range of digital applications.
