The 74ACT245SC is an integrated circuit (IC) component that is widely used for voltage level shifting and bus transceiver applications. It is part of the ACT family of ICs, which stands for Advanced CMOS Technology. The IC is designed to operate at high speeds and low power consumption, making it suitable for a wide range of digital applications.
One of the key features of the 74ACT245SC is its 8-bit bidirectional transceiver functionality. This means that it can receive and transmit data on the same set of pins, making it ideal for applications where data needs to be sent in both directions. The IC operates at a wide input/output voltage range of 2.0V to 6.0V, allowing it to interface with various logic families.
The 74ACT245SC has 8 tri-state outputs that are controlled by an Output Enable (OE) pin. This enables the user to enable or disable the output buffers as needed. The tri-state capability allows multiple devices to be connected to a common bus without interference, as the device can effectively disconnect its outputs when not in use.
Another notable feature of the 74ACT245SC is its high-speed operation. It has a typical propagation delay of 4.5 ns, making it suitable for time-critical applications. The IC also has a high output drive capability, allowing it to drive heavy capacitive loads on the bus lines
