Test Conditions / Notes
f_SCL = 400KHz
V_SDA = V_CC
WP = Vss or Open/Floating
V_SCL= V_CC (when no bus activity
else f_SCL = 400kHz)
V_IN (4) = GND to V_CC.
V_IN = V_SS to V_CC with all other
analog pins floating
V_OUT (5) = GND to V_CC.
X9521 is in Standby(2)
I_SINK = 2.0mA

The device enters the Active state after any START, and remains active until: 9 clock cycles later if the Device Select Bits in the
Slave Address Byte are incorrect; 200nS after a STOP ending a read operation; or t_WC after a STOP ending a write operation.
The device goes into Standby: 200nS after any STOP, except those that initiate a high voltage write cycle; t_WC after a STOP that
initiates a high voltage cycle; or 9 clock cycles after any START that is not followed by the correct Device Select Bits in the Slave
Address Byte.
Current through external pull up resistor not included.
V_IN = Voltage applied to input pin.
V_OUT = Voltage applied to output pin.
V_IL Min. and V_IH Max. are for reference only and are not tested
