STMicroelectronics 74LCX00MTR: Low Voltage Quad 2-Input NAND Gate

The 74LCX00MTR is a high-performance, low-voltage quad 2-input NAND gate integrated circuit from STMicroelectronics, designed to operate particularly well in 3.3V systems. It is part of the LCX family, which is known for its low consumption and high speed, making it suitable for a wide range of applications that require efficient logic operations.

This device is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining CMOS low power dissipation. The 74LCX00MTR can operate at a voltage range of 2V to 3.6V, which allows for the interfacing with 5V logic levels without the need for external components. This feature is particularly useful for mixed-voltage applications and for systems that require a transition from higher to lower voltage operation, ensuring compatibility across different logic families.

The 74LCX00MTR boasts a 5V tolerant input, which ensures that it can be used in environments where the voltage levels may fluctuate. This tolerance also means that the device can be used in bus hold circuits without the need for additional components, simplifying design and reducing overall system costs.

STMicroelectronics has designed the 74LCX00MTR with a propagation delay (t<sub>PD) that is exceptionally low, typically 4.5ns at 3.3V, making it a high-speed component suitable for fast logic operations in computing, telecommunications, and industrial applications. Additionally, its power-down protection on inputs and outputs allows for safe behavior when the device is powered off, avoiding potential damage to the circuit.

This integrated circuit comes in a Micro Package (MTR), specifically in the TSSOP14 package, which is known for its small footprint and suitability for space-constrained applications. The 74LCX00MTR is also characterized for operation from -40°C to +85°C, ensuring reliability and performance across a wide temperature range.

In summary, the STMicroelectronics 74LCX00MTR is a versatile, high-speed, low-voltage NAND gate that offers compatibility with 5V levels, low power consumption, and protection features, making it an excellent choice for designers looking to optimize their digital logic operations in various applications.
