74ACT646SC

The 74ACT646SC, a high-speed CMOS device from STMicroelectronics, is an 8-bit non-inverting buffer and line driver designed for driving loads and increasing the speed of memory address, address/data multiplexed buses and clock lines. It is designed to operate using 3.3V logic systems, and improve the speed of data propagation through the system.

74ACT646SC has many applications, especially in high-speed data and control systems. It is commonly used in computer memory applications and memory buses and is used to buffer address and data busses and clock lines to improve transfer speeds and minimize electrical disturbances. It is also commonly used in data and word transmission, digital communication settings and in digital systems.

In terms of working principle, the 74ACT646SC is a non-inverting buffer. It means that the output signal is equal to the input signal but with reduced noise. It also means that it does not have an inverting buffer. It has an open-drain architecture and is connected to a ground or power line depending on the required output. It has a Vcc range of 2.5V to 3.6V with a maximum output current of 8mA.

The 74ACT646SC has a number of features making it well suited for high-performance applications. It offers low power dissipation, low voltage operation and low static current. It also has an output enable/disable feature to minimize power consumption when the device is not in use. The device provides a latch-up immunity of 100mA and is constructed with industry-standard CMOS technology.

When using the 74ACT646SC, care should be taken to ensure that the device is used in an environment that meets the specified conditions. If used outside the specified conditions, the device may malfunction. The 74ACT646SC can be used in temperature ranges between -40°C to +85°C as well as at a maximum altitude of 3000 m.

The 74ACT646SC is a very useful device for increasing system speed and minimizing electrical disturbances. With its low power dissipation, low voltage operation and latch-up immunity, it is ideal for high-speed data and control systems. Its open-drain architecture makes it suitable for applications in which the output must be enabled or disabled. When designing systems including the 74ACT646SC, it is important to ensure that the device is used in the environment within the specified conditions.
