Functional Features

• Bidirectional Data Transfer: The 74ACT16657DLR allows data to be transferred bidirectionally between two buses.
• 3-State Outputs: The IC features 3-state outputs, enabling the bus lines to be disconnected from the internal circuitry when not in use.
• High-Speed Operation: With a maximum propagation delay of 4.5ns, this IC ensures efficient and rapid data transfer.
• Low Power Consumption: The ACT logic family used in this IC minimizes power consumption, making it suitable for battery-powered devices.

Advantages and Disadvantages

Advantages: - High-speed operation facilitates quick data transfer. - Low power consumption extends battery life in portable devices. - 3-state outputs allow for flexible bus control.

Disadvantages: - Limited number of bits (16) may not be sufficient for certain applications requiring larger data buses. - Temperature range limited to -40°C to +85°C, which may restrict usage in extreme environments.

Working Principles

The 74ACT16657DLR is designed as a 16-bit bus transceiver with 3-state outputs. It enables bidirectional data transfer between two buses by controlling the direction of data flow using the OEAB, OECD, OEF, and OEJK pins. When the output enable pins are active, the IC allows data to be transmitted from one bus to the other. The 3-state outputs provide flexibility by allowing the bus lines to be disconnected when not in use, preventing conflicts and reducing power consumption.
