ON Semiconductor MC74LCX02DTG Logic Gate

The MC74LCX02DTG from ON Semiconductor is a high-performance, quad 2-input NOR gate integrated circuit designed to operate at exceptionally high speeds with a 5V tolerant input. This advanced technology device is fabricated with silicon gate CMOS technology to achieve fast propagation delays, low ON resistances, and low power consumption. Its robust design is optimized for 3.3V VCC operation but can also function with a 2.5V power supply, offering designers a versatile component for mixed-voltage applications.

This logic gate IC is part of the LCX family, known for its capability to interface with 5V systems, making it ideal for translating signals between different voltage domains seamlessly. The MC74LCX02DTG features inputs that can tolerate voltages up to 5V, regardless of the VCC operating range, ensuring compatibility with older 5V systems, which is particularly useful during technology migration phases.

The product comes in a TSSOP-14 package, which is a space-saving and surface-mountable package, allowing for a compact PCB layout. This is particularly beneficial for high-density circuit designs where board space is at a premium. The package is also conducive to automated assembly processes, supporting efficient manufacturing and assembly of complex electronic systems.

Key features of the MC74LCX02DTG include:

• Support for 2.5V to 3.3V VCC operations with 5V tolerant inputs
• High-speed performance with propagation delays significantly lower than HC logic
• Power down high impedance inputs and outputs
• ±24mA output drive at 3.3V
• Over-voltage tolerant inputs facilitate system-level ESD protection
• Implements patented noise/EMI reduction circuitry for quiet operation
• Latch-Up Performance exceeds 500mA
• ESD performance: Human body model >2000V; Machine model >200V

With its combination of speed, low power consumption, and 5V tolerant inputs, the MC74LCX02DTG is an excellent choice for high-speed logic applications that require the interfacing of different voltage systems, such as telecommunications, computing, and industrial controls. ON Semiconductor's commitment to quality and reliability ensures that this component will perform reliably in a wide range of environmental conditions and use cases.
