74AC/ACT245SC is a quad bus transceiver with non-inverting 3-State outputs. It is built with Advanced CMOS logic, offering 4-bit parallel bidirectional data transfer between two buses. It is ideal for implementing the data transfer between varying buses and the control signals are minimal. It provides high speed and low power BiCMOS operation, offering high noise immunity to digital system noise.

74AC/ACT245SC is widely used in applications such as bus interfacing, bus bridging, and data/address buffering. By connecting the output enable (OE) and active low output enable (OL) to their respective logic levels, the device will provide either a high impedance to the bus or pass data from one bus to the other.

The 74AC/ACT245SC works by using four inverters connected to form a latch and two control lines to select the direction of the data flow. The device consists of two pairs of gate logic circuits, each with a pair of three-state bus-oriented transmission gates. Each of the two pairs can be configured to either receive or transmit data. The four section latch is used for data latching. The two control lines select the direction of data flow.

If OL is high, the device will pass data from the A bus to the B bus. If OL is low, the device will pass data from the B bus to the A bus. Similarly, if OE is high, then the four I/O pins will be in the high impedance state and the bus will be in a high impedance state. If OE is low, then the data will be either transmitted or received, depending on the state of OL.

The 74AC/ACT245SC is powered by a 5V power supply and is available in the HT, D, and N packages. This device is usually used for faster data transmission and low power consumption purposes. It also features bi-directional data transfer, which is useful for data communication applications. This device has very low power consumption and is designed to be noise immune to digital system noise.

The 74AC/ACT245SC is the ideal choice for data communication applications that require bi-directional data transfer, low power consumption, and noise immunity. This device is a convenient choice for connecting two buses that need to be bidirectionally transferred, as data will be transferred in both directions quickly and efficiently. By using this device, the number of necessary control signals for data transfer is minimal, which make it ideal for design purposes.
