Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93HC46 is manufactured using Catalyst’s advanced CMOS EEPROM floating gate PIN CONFIGURATION DIP Package (P, L) CS SK DI DO 1 2 3 4 8 7 6 5 VCC NC ORG GND SOIC Package (J, W) NC VCC CS SK SOIC Package (S, V) MSOP Package (R, Z) CS SK DI DO 1 2 3 4 8 7 6 5 VCC NC ORG GND CS SK DI DO 1 2 3 4 8 7 6 5 VCC NC ORG GND CS SK DI DO D 1 2 3 4 TSSOP Package (U, Y) 8 7 6 5 VCC NC ORG GND is o c 1 2 3 4 8 7 6 5 ORG GND DO DI i t n u n CS SK DI DO VCC technology.

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. D.C.

During transitions, inputs may undershoot to -2.0 V for periods of less than 20 ns. Maximum DC voltage on output pins is VCC + 0.5 V, which may overshoot to VCC + 2.0 V for periods of less than 20 ns. (2) Output shorted for no more than one second. (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 I/O pins from -1 V to VCC + 1 V. (5) Standby Current (ISB2) = 0 µA (
