DESCRIPTION/ORDERING INFORMATION

PCA9518

SCPS132A – JUNE 2006 – REVISED JULY 2007

• Expandable Five-Channel Bidirectional Buffer

• Operating V

• Latchup Performance Exceeds 100 mA Per

JESD 78

Support Mixed-Mode Signal Operation

• ESD Protection Exceeds JESD 22

• Active-High Individual Repeater Enable Inputs

–

2000-V Human-Body Model (A114-A)

• Open-Drain Input/Outputs

–

200-V Machine Model (A115-A)

• Lockup-Free Operation

–

1000-V Charged-Device Model (C101)

• Supports Arbitration and Clock Stretching

Across the Repeater

• Supports Multiple Masters

and clock (SCL) lines into multiple groups of 400-pF segments. Any segment-to-segment transition sees only

one repeater delay. Each PCA9518 can communicate with other PCA9518 hubs through a 4-wire inter-hub

expansion bus. Using multiple PCA9518 parts, any width hub (in multiples of five) can be implemented using the

expansion pins, with only one repeater delay and no functional degradation of the system performance.
