The PI74FCT16245ATAE is a member of Fairchild Semiconductor’s FCT Series of low-voltage, full-function, 3.3V CMOS logic gates for the consumer, communication, and computing markets. This device is a high-performance, 16-bit bus buffer used for bidirectional data flow between two buses. It is typically used to provide buffer memory from 16-bit wide buses to support external sources, such as disk controllers, so that fast data transfer can occur between the two buses. The PI74FCT16245ATAE can be used in a variety of applications such as memory expansion, memory protection, bus bridge, bus transceivers, bus arbitration and bus fan-out.

The PI74FCT16245ATAE offers an impressive combination of features. It has three-state outputs, which allows it to accept or reject data; it has programmable data direction control; it has a gatable output register clock; it has an active low output-enable (OE) control pin; and it has a power-saving sleep mode.

The PI74FCT16245ATAE is well suited for applications that require high-speed data transfer rates. It features a 10-bit addressable output register and a 10-bit addressable input register, both of which support data transfer rates up to 66MHz. The device also offers low propagation delay of 6ns and low power consumption. It is available in a 48-pin, 0.65mm pitch, plastic TQFP package.

In terms of operating principles, the PI74FCT16245ATAE has two parts: an input register and an output register. All the bits of the input register are loaded into the output register when the output register clock is activated. The output register stores its bits until the output register clock is activated again. The data becomes visible at the output when the output-enable control pin is active. When the output-enable signal is inactive, the outputs are in a high-impedance state.

The PI74FCT16245ATAE can be used in a variety of applications, from memory expansion and memory protection to bus fan-out, tap switches, and so on. It is a versatile device that can provide an efficient, low-cost solution for high-speed data transfer. In addition, it can be used in circuits that require multiple inputs to drive a single output, such as multiplexers or demultiplexers.

In summary, the PI74FCT16245ATAE is a 16-bit, full-function 3.3V CMOS logic gate with two parts: an input register and an output register. Its features include three-state outputs, programmable data direction control, gatable output register clock, low power consumption and active low output-enable control pin. It is ideally suited for applications that require high-speed data transfer rates and can be used in a variety of applications, from memory expansion and memory protection to bus fan-out, tap switches and multiplexers. With its impressive combination of features, the PI74FCT16245ATAE is an ideal solution for high-speed data transfer.
