DESCRIPTION
The CAT33C704 is a 4K-bit Serial E2PROM that safe-
guards stored data from unauthorized access by use of
a user selectable (1 to 8 byte) access code and a
movable memory pointer. Two operating modes provide
unprotected and password-protected operation allow-
ing the user to configure the device as anything from a

Note:
(1) DI, DO may be tied together to form a common I/O.
ROM to a fully protected no-access memory. The
CAT33C704 uses a unique serial-byte synchronous
communication protocol and has a Sequential Read
feature where data can be sequentially clocked out of
the memory array. The device is available in 8-pin DIP
or 16-pin SOIC packages.

*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.

Test Conditions
VCC = 3.3V, CS = VCC
DO is Unloaded.
VCC = 3.3V, CS = 0V
DI = 0V, CLK = 0V
IOL = 2.1mA
IOH = –400µA
VIN = 3.3V
VOUT = 3.3V, CS = 0V
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) PE pin test conditions: VIH < VIN < VIL
