specification. Phillips only defines the field types, field
lengths, timings, etc. of a frame. The frame content
defines the behavior of the device. The frame content
for the MCP4017, MCP4018, and MCP4019 devices
are defined in this section of the Data Sheet.

devices may be operating on separate power supply
sources, ESD clamping diodes are not permitted. The

tied to V
specification makes some general recommendations
on the size of this pull-up, but does not specify the
exact value since bus speeds and bus capacitance
impacts the pull-up value for optimum system
performance.
Common pull-up values range from 1 k

higher values to minimize current losses during
communication but these applications also typically
utilize lower V
The SDA and SCL float (are not driving) when the
device is powered down.
A "glitch" filter is on the SCL and SDA pins when the pin
is an input. When these pins are an output, there is a
slew rate control of the pin that is independent of device
frequency.

The device implements slope control on the SDA
output. The slope control is defined by the fast mode
specifications.
For Fast (FS) mode, the device has spike suppression
and Schmidt trigger inputs on the SDA and SCL pins.
