5 / 14 page CAT705, CAT706, CAT813 © Catalyst Semiconductor, Inc. 5 Doc. No. MD-3030, Rev. A Characteristics subject to change without notice ELECTRICAL OPERATING CHARACTERISTICS (continued) VCC = 4.50V to 5.5V for CAT705, CAT706 & CAT813 versions; VCC = 3.0V to 3.6V for the CAT706 R/S/T version, -40°C ≤ TA ≤ +85°C unless otherwise noted. Typical values at TA = 25°C and VCC = 5V for CAT705, CAT706, & CAT813 versions; VCC = 3.3V for the CAT706 T/S versions; VCC = 3.0V for the CAT706 R version.

(4) The WDI input current is specified as an average input current when the WDI input is driven high or low. The WDI input if connected to a three-stated output device can be disabled in the tristate mode as long as the leakage current is less than 10µA and a maximum capacitance of less than 200pF. To clock the WDI input in the active mode the drive device must be able to source or sink at least 200µA when active. (5) RESET ¯¯¯¯¯¯ for CAT705 & CAT706 & RESET for CAT813. |
