The PI74FCT244TQE is an eight-bit noninverting buffer and driver made by Pericom Semiconductor Corporation. This buffer and driver is designed with 3–state outputs designed for applications where data need to be transferred between different logic families, such as Low–Voltage/Low–Power (LVTTL), Pericom Low–Voltage Differential Signaling (PLVDS) and TTL. The PI74FCT244TQE is classified under Logic - Buffers, Drivers, Receivers and Transceivers, and is capable of providing high frequency operation, with enable/disable for efficient design flexibility.

The PI74FCT244TQE consists of the following features: logic controlled interface for LVTTL, LVPECL and PLVDS systems; logic controlled interface for TTL systems; logic controlled order for Triple–State outputs; logic–controlled outputs; and order input. This product is made with a ceramic/ceramic package, and an operating temperature range from 0°C to 70°C.

The PI74FCT244TQE is mainly used in high frequency communications, such as repeaters and switches, where the high frequency signals need to be buffered and driven. This buffer and driver is also used in clock tree applications, since it offers flexible input/output configurations and fast switching at higher frequencies. The PI74FCT244TQE is suitable for input/output applications with varying voltage levels, since it allows high performance interface design between different logic families.

The PI74FCT244TQE operates according to the following principles. First of all, it accepts the input data which is received from the source logic family, such as LVTTL, LVPECL and other TTL systems, and then it uses this data to drive the outputs of the target logic family. The inputs are provided with logic control, meaning that it can be turned on and off via a control signal. The order input is used to control the order of the outputs, and it also has the ability to toggle all of the outputs between logic states.

The outputs on the PI74FCT244TQE come in two different formats; either 3–state or logic controlled. When the outputs are set to 3–state, the logic signal is floating, which allows the user to transmit data securely. When the outputs are set to logic–controlled, the driver is capable of driving the data signals according to the logic signal given. The PI74FCT244TQE also offers the option to enable/disable all of the outputs, in order to ensure efficient design flexibility.

Overall, the PI74FCT244TQE is a high performance 8–bit noninverting buffer and driver that is designed for applications which require high speed data transmission between different logic families. It also provides logic controlled order with tri–state outputs, logic controlled inputs and ordering input, and can be enabled/disabled via a control signal. This device is ideal for high frequency communication, clock tree applications and interface design between varying voltage levels, since it is capable of providing fast switching at higher frequencies and secure data transmission.
