I2C IO Pad Set

Features

• Product Features
• • Supported I2C operating modes:
• o Standard-mode (Sm) – 100 Kbps data rate
• o Fast mode (Fm) – 400 Kbps data rate
• o Fast mode (Fm+) – 3.4 Mbps data rate
• • Open drain operation only (floating NWELL with PMOS
• used for ESD protection only)
• • Built-in output slew rate control to meet I2C Tof minimum of
• (20 x VDDP/5.5V) ns
• • Output enable
• • Receiver enable
• • ESD protection uses snap-back devices (no diode to the
• positive power supply)
• • Standard LVCMOS compatible inputs with Schmitt trigger
• (hysteresis) option
• • Power-on sequencing independent design with Power-On
• Control
• • DVDD = 2.7V to 3.63V
• • Pad VDDP (power supply reference for Output) = 2.7V to
• 3.63V, limited to VDVDD.
• • The circuit consumes no DC supply current in the static state
