Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
Table 4. ELECTRICAL OPERATING CHARACTERISTICS
(V_CC = Full range, T_A = −40°C to +85°C unless otherwise noted. Typical values at T_A = +25°C and V_CC = 5 V for the L/M/J versions,
V_CC = 3.3 V for the T/S versions, V_CC = 3 V for the R version and V_CC = 2.5 V for the Z version.)

1. Production testing done at T_A = +25°C; limits over temperature guaranteed by design only.
2. Glitches of 100 ns or less typically will not generate a reset pulse.
3. RESET output for the CAT811; RESET output for the CAT812.
