CAT811, CAT812
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.
