Temperature Ranges
The CAT24WC01/02/04/08/16 is a 1K/2K/4K/8K/16K-
bit Serial CMOS E2PROM internally organized as 128/
256/512/1024/2048 words of 8 bits each. Catalyst’s
advanced CMOS technology substantially reduces de-
vice 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.

*COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of
the device at these or any other conditions outside of those
listed in the operational sections of this specification is not
implied. Exposure to any absolute maximum rating for
extended periods may affect device performance and
reliability.

Note:
(1) The minimum DC input voltage is –0.5V. 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).
