  • 8-bit direction controlled translating bus transceiver
  • 2.3V to 3.6V on A port and 3V to 5.5V on B port
  • Robust, glitch-free power supply sequencing
  • VCC isolation and VCC Disconnect feature
    • If either VCC input is below 100mV or left floating, all I/O outputs are disabled and become high impedance
  • Control inputs VIH and VIL levels are referenced to VCCA voltage
  • High drive strength for heavier loads: 24mA drive at 3V supply
  • Latch-up performance exceeds 250mA per JESD 17
  • Operating temperature range from -40°C to 85°C
  • ESD protection exceeds JESD 22
    • 2000V Human Body Model (A114-A)

The SN74LVCC3245A device is an 8-bit (octal) noninverting bus transceiver contains two separate supply rails. The B port is designed to track VCCB, which accepts voltages from 3V to 5.5V, and the A port is designed to track VCCA, which operates at 2.3V to 3.6V. This allows for translation from a 3.3V to a 5V system environment and vice versa, from a 2.5V to a 3.3V system environment and vice versa.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The VCC isolation feature is designed so that if either VCCA or VCCB is less than 100mV, both I/O ports enter a high-impedance state by disabling the outputs.
