  • Supports both 3.3V and 2.5V systems
  • 3-state outputs allow multiple devices to share a common bus
  • Provides voltage translation without the need for external level shifters
  • High-speed operation allows for efficient data transfer

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems - High-speed operation enables fast data transmission - Non-inverting functionality simplifies circuit design - 3-state outputs facilitate bus sharing among multiple devices

Disadvantages: - Limited to 16-bit data transmission - Requires careful consideration of voltage levels to prevent signal degradation

Working Principles

The SN74ALVCH16269DL operates by receiving data from one voltage domain (Port A) and transmitting it to another voltage domain (Port B), or vice versa. The non-inverting nature of the device ensures that the logic levels are preserved during the translation process. The Output Enable (OE) pin controls the direction of data flow and can be used to disable the outputs when necessary.
