Catalyst’s advanced CMOS technology substantially reduces device power requirements. The the CAT24WC01/02/04/ 08/16 feature a 16-byte page write buffer. The device operates via the I2C bus serial interface, has a special write protection feature, and is available in 8-pin DIP, 8- pin SOIC or 8-pin TSSOP.

During transitions, inputs may undershoot to –2.0V for periods of less than 20 ns. Maximum DC voltage on output pins is VCC +0.5V, which may overshoot to VCC + 2.0V for periods of less than 20ns. (2) Output shorted for no more than one second. No more than one output shorted at a time. (3) This parameter is tested initially and after a design or process change that affects the parameter. (4) Latch-up protection is provided for stresses up to 100 mA on address and data pins from –1V to VCC +1V. (5) Standby Current (ISB) = 0µA (<900nA). Doc.
