74LVT08DB,112 - Logic Gates and Inverters

The 74LVT08DB,112 is an integrated circuit of logic gates and inverters developed by SGS-Thomson Microelectronics. It is an eight-level voltage tolerant CMOS logic device which provides logic level compatibility between 3.3 V, 5 V, and 12 V power supplies. In addition, 74LVT08DB,112 is designed to provide registration and address data bus expansion between voltage levels and the expansion of address bus signals between the processors and interface devices. The 74LVT08DB,112 has an operating temperature range of −40 °C to +85 °C.

Features

The 74LVT08DB,112 has several features that make it a reliable and cost-effective logic device to use in circuit design. These include: high speed, as it can operate with up to 24 MHz; low power consumption; and industry-standard TTL compatibility. Furthermore, the device includes an input clamp diode allowing for protection from overvoltage transients, and features an output enable terminal which can be used to disable all outputs.

Application fields

The 74LVT08DB,112 is an ideal choice for a wide range of applications, such as: digital logic interface, data storage and transmission, memory buffer, logic gates and inverters, interface between TTL logic and the MOSI-BUS and TTL logic. It is suitable for applications in desktop computers, printers, embedded systems, medical equipment, robotics, and so forth.

Working principle

The 74LVT08DB,112 is a TTL/CMOS compatible logic device which contains two type of logic families-TTL and CMOS. TTL stands for \'Transistor Transistor Logic\', and is a form of digital logic based on circuitry involving transistors and resistors, while CMOS stands for \'Complementary Metal Oxide Semiconductor\', and is a type of logic involving circuits composed of field effect transistors and resistors.The 74LVT08DB,112 consists of eight identical CMOS inverters, where each inverter is composed of a pull-up P-channel transistor and a pull-down N-channel transistor. When the device is powered, the P-channel transistor will be on to conduct current, while the N-channel transistor will be off. When data is applied to the input of the inverter chip, the P-channel transistor will switch off, and the N-channel transistor will turn on. This inversion process produces an inverted version of the input data at the output of the chip.

Conclusion

The 74LVT08DB,112 is a versatile logic device that can be used to increase the speed and performance of digital logic interfaces. It provides compatibility between different logic families and is suitable for a wide range of applications, including memory buffering and logic gates and inverters. The device also has a wide temperature range, making it suitable for use in a range of environmental conditions.
