All voltages referenced to ground.
The DS4510 does not obstruct the SDA and SCL lines if V_CC is switched off, as long as the voltages applied to these
inputs do not violate their min and max input voltage levels.
ISTBY specified with V_CC equal to 5.0V, and control port-logic pins are driven to ground or V_CC for the corresponding
inactive state (SDA = SCL = V_CC), does not include pullup resistor current.
See Typical Operating Characteristics for the RST output voltage vs. supply voltage.
This parameter is guaranteed by design.
I²C interface timing shown for is for fast-mode (400kHz) operation. This device is also backward compatible with I²C
standard-mode timing.
CB—total capacitance of one bus line in picofarads.
EEPROM write time applies to all the EEPROM memory and SEEPROM memory when SEE = 0. The EEPROM write time
begins at the occurrence of a stop condition.
(V_CC = +5.0V, T_A = +25°C, unless otherwise noted.)
