Supply voltage
Input high voltage: Logic 1; All inputs
Input low voltage: Logic 0; All inputs
Output low voltage: Iout = 3mA
Input leakage current: Vin = GND to Vdd
Output leakage current: Vout = GND to Vdd
Standby current: SCL = SDA = Vdd - 0.3V; All other inputs = Vss or Vdd
Power supply current: SCL clock frequency = 100 kHz

Notes:
1. To avoid spurious start and stop conditions, a minimum delay is placed between SCL = 1 and
2. This parameter is sampled.
3. For a restart condition or following a WRITE cycle.

sequence to the end of the EEPROM internal ERASE/PROGRAM cycle. During the WRITE
cycle, the EEPROM bus interface circuit is disabled, SDA remains HIGH due to pull-up resis-
tance, and the EEPROM does not respond to its slave address.
