The SN74ALVCH16543DL is a high-speed, 16-bit universal bus transceiver and register designed for 2.7V to 3.6V VCC operation with 5V tolerant inputs and outputs. It offers a wide range of features and functions that make it an excellent choice for various applications. Here is an overview of its key features:
1. Universal Bus Transceiver: The SN74ALVCH16543DL acts as a bidirectional buffer between two independent buses, offering simple bus interfacing and signal level translation capabilities.
2. 16-bit Register: It incorporates a 16-bit parallel-in/parallel-out register that operates synchronously to the positive edge of the clock (CLK) signal. The register can hold the data from the A bus and release it to the B bus or vice versa, depending on the direction control (DIR) input.
3. Direction Control: The DIR input determines the direction of data flow through the SN74ALVCH16543DL. When DIR is low, data flows from the A bus to the B bus, and when high, it flows from B to A.
4. Output Enable Control: The output enable (OE) input allows the user to place the outputs into a high-impedance state. This feature enables easy system interfacing by disconnecting the outputs from the buses when they are not needed
