REMOTE 16-BIT I2C AND SMBus, LOW-POWER I/O EXPANDER

WITH INTERRUPT OUTPUT AND CONFIGURATION REGISTERS

SCPS129E – AUGUST 2005 – REVISED FEBRUARY 2007

PARAMETER MEASUREMENT INFORMATION (continued)

CL includes probe and jig capacitance.

All inputs are supplied by generators having the following characteristics: PRR

≤ 10 MHz, Z

O = 50 Ω, tr/tf ≤ 30 ns.

The outputs are measured one at a time, with one transition per measurement.

I/Os are configured as inputs.

All parameters and waveforms are not applicable to all devices.
