4 / 11 page CAT811, CAT812 Doc. No. MD-3005 Rev. S 4 © Catalyst Semiconductor, Inc. Characteristics subject to change without notice ELECTRICAL OPERATING CHARACTERISTICS (continued) VCC = Full range, TA = -40°C to +85°C unless otherwise noted. Typical values at TA = +25°C and VCC = 5V for the L/M/J versions, VCC = 3.3V for the T/S versions, VCC = 3V for the R version and VCC = 2.5V for the Z version.
