DS4520
9-Bit I2C Nonvolatile
I/O Expander Plus Memory
_____________________________________________________________________

Note 1: All voltages referenced to ground.
Note 2: ISTBY is specified with SDA = SCL = VCC, outputs floating, and inputs connected to VCC or GND.
Note 3: The DS4520 does not obstruct the SDA and SCL lines if VCC is switched off as long as the voltages applied to these inputs
do not violate their minimum and maximum input voltage levels.
Note 4: Guaranteed by design.
Note 5: Timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with I
2C standard-mode timing.
Note 6: CB—total capacitance of one bus line in picofarads.
Note 7: EEPROM write time applies to all the EEPROM memory and SRAM shadowed EEPROM memory when SEE = 0. The EEPROM
write time begins after a stop condition occurs.
AC ELECTRICAL CHARACTERISTICS (See Figure 2)
(VCC = +2.7V to +5.5V; TA = -40°C to +85°C, unless otherwise noted. Timing referenced to VIL(MAX) and VIH(MIN).)
