The \'74ACT240 is a high-speed octal buffer/line driver and receiver with differential active bus pins designed to allow easy interface with standard industry buses. It is designed to meet the industry standard communication bus requirements and features a power-up clear function, direct pin-to-pin equivalence with other members of the ‘74ACT family, and advanced silicon-gate CMOS technology. This article will cover the application field and working principle of the ‘74ACT240.ApplicationsThe \'74ACT240 is most commonly used in address and data bus applications that are required to interface with external circuitry. It is designed to provide high-speed buffered bus control and can be used in variety of applications as it is compatible with both ECL and CMOS logic families. It is used in many systems that require interfacing with standard industry buses such as for VMEbus, Multibus, and IBM-PCs.The \'74ACT240 can also be used in a variety of other applications. For example, it can be used as an octal buffer/line driver in communications and multi-processor systems. It can also be used as a line driver in optical systems and computer networks.Working PrincipleThe \'74ACT240 comprises an octal buffer/line driver circuit and a receiver. The buffer/line driver consists of eight differential pairs of TTL-compatible buffers/line drivers, each of which can be individually enabled/disabled. The output of each buffer/line driver is differential and is typically used to drive a pair of twisted-pair wires or other transmission mediums.The receiver of the \'74ACT240 consists of eight differential pairs of inputs. When enabled, each input will monitor the differential input lines. When the differential voltage is greater than the receiver threshold, an input is asserted and the corresponding output will be asserted.The \'74ACT240 is designed to have both input and output directions available at the same time, allowing for bidirectional data transfer. The outputs are actively driven by the line drivers, yet the receiver inputs will not be affected by the output drivers.ConclusionThe \'74ACT240 is a versatile octal buffer/line driver and receiver with a range of practical applications. It is ideal for interfacing with industry standard buses and can be used in communications and multi-processor systems,Optical systems and computer networks. Its differential active bus pins make it perfect for bidirectional data transfer.
