Table 4. ELECTRICAL OPERATING CHARACTERISTICS (Typical values at T_A = 25°C and V_CC = 5 V for CAT705, CAT706 and
CAT813 versions. V_CC = 3.3 V for the CAT706 T/S versions; V_CC = 3.0 V for the CAT706 R version.) (Note 1)

1. Limits are guaranteed by design and not production tested.
2. The RESET short−circuit current is the maximum pull−up current when reset is driven low by a bidirectional output.
3. WDI is internally serviced within the watchdog period if WDI is left open.
4. RESET for CAT705 & CAT706 & RESET for CAT813.
5. Not 100% tested but guaranteed by design.
