Additional Details
The PI74FCT245TQX includes a direction control (DIR) input, which determines the direction of data flow through the device. The output enable (OE) input controls whether the outputs are active or in a high-impedance state. The device minimizes propagation delay, skew, and ground bounce for high-speed operation. Refer to the datasheet for specific operating temperature ranges, voltage ranges, and other electrical characteristics. The 'QX' suffix refers to a specific packaging or quality standard; refer to the datasheet for specifics on this. This transceiver is commonly used where bi-directional data transfer at high speeds is needed and proper bus isolation is necessary.
