Functional Features

  • Bidirectional voltage-level translation between different logic families.
  • 3-state outputs allow multiple devices to share a common bus.
  • High-speed operation with minimal propagation delay.
  • Output enable control for easy bus management.

Advantages

  • Enables seamless communication between different logic families.
  • Supports high-speed data transmission.
  • Allows multiple devices to share a common bus, reducing the number of required pins.
  • Provides reliable voltage-level translation with minimal propagation delay.

Disadvantages

  • Limited to specific logic families (ABT in this case).
  • Requires careful consideration of input and output voltage levels to ensure proper operation.
  • May not be suitable for applications requiring very low power consumption.

Working Principles

The 74ABT16245BDGG-Q1J operates by receiving data inputs from one logic family and translating them into compatible voltage levels for another logic family. The direction of data flow is controlled by the DIR pin. When the output enable (OE) pin is active, the device allows bidirectional data transfer. When the OE pin is inactive, the outputs are in a high-impedance state, effectively disconnecting the device from the bus.

Detailed Application Field Plans

The 74ABT16245BDGG-Q1J can be used in various applications that require voltage-level translation
