The HD74LVCZ245AFPEL is an octal bus transceiver with 3-state outputs manufactured by Renesas Electronics America. This device is designed for high-performance bi-directional data communication on parallel buses. It features eight transceivers with direction control, allowing for versatile control of data flow. The 3-state outputs provide isolation when disabled, preventing bus contention. It is designed with a low quiescent current (Z suffix) to minimize power consumption when the outputs are disabled.

Additional Details
The HD74LVCZ245AFPEL features a typical propagation delay of around 4 ns at 3.3V. It is available in the SOP (Small Outline Package) package. This device is designed to be compatible with LVTTL (Low-Voltage Transistor-Transistor Logic) voltage levels, allowing for seamless integration with other logic components. The direction control pin allows for selection of either A-to-B or B-to-A data transfer. The output enable pin allows for disabling the outputs, placing them in a high-impedance state. The device's outputs are capable of driving moderate capacitive loads, making it suitable for a variety of bus interface applications. The Z suffix indicates a very low quiescent current, important for power-sensitive applications. It adheres to industry standard electrostatic discharge (ESD) protection levels, providing added reliability in handling and operation.
