FEATURES
• High-bandwidth data path (up to 500 MHz)1
• 5-V tolerant I/Os with device powered up or powered down
• Low and flat ON-state resistance (ron) characteristics
over operating range (ron = 3 Ω typical)
• Supports input voltage beyond supply on data I/O ports
– 0 to 5 V switching with 3.3 V VCC
– 0 to 3.3 V switching with 2.5 V VCC
• Bidirectional data flow with near-zero propagation delay
• Low input or output capacitance minimizes loading
and signal distortion (Cio(OFF) = 3.5 pF typical)
• Fast switching frequency (fOE = 20 MHz maximum)
• Data and control inputs provide undershoot clamp diodes
• Low power consumption (ICC = 0.25 mA typical)
• VCC operating range from 2.3 V to 3.6 V
• Data I/Os support 0 to 5 V signaling levels (0.8 V,
1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V)
• Control inputs can be driven by TTL or 5 V/3.3 V
CMOS outputs
• Ioff supports partial-power-down mode operation
• Latch-up performance exceeds 100 mA per JESD78, Class II
