device reliability.

Table 4. ELECTRICAL OPERATING CHARACTERISTICS

(VCC = Full range, TA = −40°C to +85°C unless otherwise noted. Typical values at TA = +25°C and VCC = 5 V for the L/M/J versions,

VCC = 3.3 V for the T/S versions, VCC = 3 V for the R version and VCC = 2.5 V for the Z version.)

1. Production testing done at TA = +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.
