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.

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