I2C Compatibility
The MAX4399 is compatible with existing I2C systems.
SCL and SDA are high-impedance inputs. SDA has an
open drain that pulls the data line low during the 9th
clock pulse. Figure 8 shows a typical I2C interface
application. The communication protocol supports the
standard I2C 8-bit communications. The general call
address is ignored, and CBUS formats are not supported.
The MAX4399 address is compatible with the 7-bit I2C
addressing protocol only. No 10-bit formats are support-
ed. RESTART protocol is supported, but an immediate
STOP condition is necessary to update the MAX4399.
Digital Inputs and Interface Logic
The I2C-compatible, 2-wire interface has logic levels
defined as VOL = 0.8V and VOH = 2.0V. All of the inputs
include Schmitt-trigger buffers to accept slow-transition
interfaces. The digital inputs are compatible with 3V
CMOS logic levels.
INTERRUPT_OUT Signal
INTERRUPT_OUT is an open-drain output that
becomes high impedance when a change in any of the
slow-switch signals occurs. Clear INTERRUPT_OUT by
setting bit 3 of register 04h low.
