PI74FCT245DTQE

The PI74FCT245DTQE device is a member of the Fairchild Semiconductor 74FCT logic family. It is a high-performance, low-power, low-voltage, dual-channel transceiver that is ideal for bidirectional data bus communications transmission. It has a low profile design and a standard TSSOP-24 package. It is synchronous with the system\'s clock and, when used properly, provides high output drive current and improved switching performance. Prior to using this device, the user must carefully read, understand and follow the device\'s data sheet to ensure proper operation.

The PI74FCT245DTQE has several application areas. It is most often used as a bidirectional transceiver for data bus communications transmission that connects logic inputs to the bus and provides an interface between the bus and system logic outputs. Its transceivers are also used in circuit designs involving asynchronous communication, such as RS-232, RS-485, and Ethernet. Additionally, it can be utilized as a bus transceiver for the Ethernet standard.

The PI74FCT245DTQE is designed to be powered by either a single +3.3V or a combination of +3.3V and +-5V power supply. Generally speaking, it functions as an 8-bit bi-directional bus transceiver, with three-state outputs. It contains two separate 8-bit transceiver channels for data transmission. Each of the two channels runs in full-duplex mode, so it can transmit and receive data at the same time.

The PI74FCT245DTQE features high-performance circuitry that allows it to operate at very low power consumption. Its active output low level is approximately 5.8mA while its standby current consumption is only 25μA. Low power consumption makes this device ideal for mobile and battery-powered applications, as well as systems where power conservation plays an important role.

The functionality of the PI74FCT245DTQE is based on the simple principle of transferring digital data between two devices, one sending and one receiving. Both input and output stages of this buffer feature a three-state latch that allows the user to select either a hi-impedance or logic low/high state. When the buffer is not in an active state, its outputs are placed in a high-impedance state, allowing the outputs of other circuits to drive their respective lines. Additionally, the input of the required buffer will be placed in a high impedance state, to prevent the drive of multiple drivers on a single data line.

The PI74FCT245DTQE features several features that make it perfect for many applications, such as its low power usage, low profile design and its ease of integration into existing systems. With a high-speed clock rate of 33MHz and an impressive fan out of 32, this device is capable of handling demanding data transmission. The PI74FCT245DTQE is not only an ideal solution for many applications, but also a reliable, cost-effective and robust buffer device that ensures successful communication between two digital devices.
