CAT809 Datasheet, PDF (5/13 Pages) Catalyst Semiconductor – 3-Pin Microprocessor Power Supply Supervisors

CAT809, CAT810
ELECTRICAL CHARACTERISTICS (continued)
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
L/M/J versions, V_CC = 3.3 V for T/S versions, V_CC = 3 V for R version and V_CC = 2.5 V for Z version.
