Manufacturer: Texas Instruments (TI)

Part Number: SN74AVCH2T45DCUR

Description:

The SN74AVCH2T45DCUR is a dual-bit, dual-supply bus transceiver designed for asynchronous communication between data buses operating at different voltage levels. It features configurable voltage-level translation, allowing seamless interfacing between devices with different supply voltages.

Key Features:

  • Voltage Translation: Supports bidirectional voltage translation between 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes.
  • Dual-Supply Operation: VCCA (Port A) and VCCB (Port B) can be independently powered.
  • Direction Control: Uses a DIR pin to control data flow (A→B or B→A).
  • High-Speed Operation: Supports up to 500 Mbps data rate.
  • Low Power Consumption: Features partial power-down (Ioff) protection to prevent backflow current.
  • ESD Protection: Exceeds 2000V HBM (Human Body Model) for robust performance.
  • Package: 8-pin VSSOP (DCU) for space-constrained applications.

Applications:

  • Mixed-voltage systems (e.g., microcontrollers, FPGAs, ASICs).
  • Mobile devices, IoT, and embedded systems.
  • Level shifting in communication interfaces (UART, SPI, I2C).

This device ensures reliable bidirectional voltage translation with minimal propagation delay, making it suitable for high-speed digital systems.
