  • 3-state outputs for bus-oriented applications
  • Register for storing data before transmission
  • High-speed operation for efficient data transfer
  • Low-power consumption for energy efficiency
  • ESD protection for improved reliability

Advantages and Disadvantages

Advantages: - High-speed operation allows for quick data transfer - Low-power consumption helps in reducing energy usage - Bidirectional data flow with direction control offers flexibility - ESD protection enhances the reliability of the IC

Disadvantages: - Limited number of bits (16) may not be suitable for certain applications requiring larger data storage - Temperature range (-40°C to +85°C) may not be suitable for extreme environments

Working Principles

The SN74ABT16657DGGR is a 16-bit registered transceiver that allows bidirectional data transfer between two buses. The direction of data flow is controlled by the DIR pin. When DIR is high, data flows from A1-A8 to B1-B8, and when DIR is low, data flows from B1-B8 to A1-A8.

The CLK input synchronizes the data transfer, and the OE# pin enables or disables the outputs. The registered data output pins (Q1-Q8) store the data before transmission, ensuring reliable and synchronized data transfer.
