• Pin 21: Clock Input (CLKBA)
• Pin 22: Master Reset (MR)

Section B: Register

• Pins 23-30: Parallel Data Inputs (A0-A7)
• Pins 31-38: Parallel Data Outputs (Q0-Q7)
• Pin 39: Output Enable (OE)
• Pin 40: Clock Input (CLK)
• Pin 41: Master Reset (MR)

Functional Features

• Bidirectional data transfer between two independent buses.
• Non-inverting outputs for both data and control signals.
• Separate output enable and direction control pins for each bus.
• Asynchronous master reset to clear the register contents.
• High-speed operation with low power consumption.

Advantages and Disadvantages

Advantages

• Supports high-speed data transfer.
• Low power consumption.
• Provides bidirectional communication between buses.
• Easy integration into existing systems.
• Reliable and robust performance.

Disadvantages

• Limited number of parallel data inputs/outputs (8 bits).
• Requires careful handling due to its small size.

Working Principles

The 74ACT16652DLG4 IC functions as a bidirectional transceiver and register. It allows data to be transferred bidirectionally between two independent buses, while also providing storage capability in the form of an 8-bit register. The direction of data flow is controlled by the DIR pin, and the output enable pins (OEAB, OEBA, and OE) allow individual bus control. The CLKAB, CLKBA, and CLK pins provide clocking signals for the respective sections. The MR pins serve as asynchronous master reset inputs, allowing the register contents to be cleared.

Detailed Application Field Plans

The 74ACT16652DLG4 IC finds applications in various fields where high-speed data transfer and storage are required. Some potential application areas include:

1. Data Communication Systems
2. Networking Equipment
3. Industrial Automation
4. Automotive Electronics
5. Test and Measurement Instruments
