1 Features

  • Fully configurable dual-rail design allows each port to operate from 1.1 V to 5.5 V
  • Robust, glitch-free power supply sequencing
  • Up to 420-Mbps support for 3.3 V to 5.0 V
  • Schmitt-trigger inputs allow for slow or noisy inputs
  • I/Os with integrated dynamic pull-down resistors help reduce external component count
  • Control inputs with integrated static pull-down resistors allow for floating control inputs
  • High drive strength (up to 32 mA at 5 V)
  • Low power consumption:
    • 4-µA maximum (25°C)
    • 12-µA maximum (–40°C to 125°C)
  • VCC isolation and Vcc disconnect (Ioff-float) feature
    • If either VCC supply is < 100 mV or disconnected, all I/Os get pulled-down and then become high-impedance
  • Ioff supports partial-power-down mode operation
  • Compatible with LVC family level shifters
  • Control logic (DIR and OE) are referenced to VCCA
  • Operating temperature from –40°C to +125°C
  • Latch-up performance exceeds 100 mA per JESD 78, Class II
  • ESD protection exceeds JESD 22
    • 4000-V Human-Body Model
    • 1000-V Charged-Device Model
