FEATURES

• High-bandwidth data path (up to 500MHz)

• 5V Tolerant I/Os with device powered up or powered 

  down

• Low and flat on-state resistance (ron)
  characteristics over operating range (ron= 4Ω typical)
• Rail-to-rail switching on data I/O ports
  – 0- to 5V Switching with 3.3V VCC
  – 0- to 3.3V Switching with 2.5V VCC
• Bidirectional data flow with near-zero propagation delay
• Low input and output capacitance minimizes
  loading and signal distortion (Cio(OFF) = 3.5pF typical)
• Fast switching frequency (f OE = 20MHz maximum)
• Data and control inputs provide undershoot clamp diodes
• Low power consumption (ICC = 0.7mA typical)
• VCC Operating range from 2.3V to 3.6V
• Data I/Os support 0- to 5V signaling levels (0.8V,
  1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V)
• Control inputs can be driven by TTL or 5V and
  3.3V CMOS outputs
