Additional Details

The IDT74FCT163373CPAG operates from a 3.3V power supply. The device features a three-state output, allowing it to be disabled from the bus when not in use. The control pins include latch enable (LE) and output enable (OE). When LE is high, the Q outputs follow the data inputs. When LE is low, the Q outputs are latched and retain their previous values. The OE pin, when low, enables the outputs; when high, the outputs are in the high-impedance state. The input and output capacitance are typically very low to minimize loading effects on the bus. The device is designed to minimize ground bounce during switching, further improving system performance. This part is commonly used in systems where temporary storage of data being transferred across a bus is required, such as in communication systems, data acquisition systems, and embedded control applications.
