NOTES:
1. Production testing done at TA = +25
°C, over temperature limits by design.
2. RESET output for TCM809, RESET Output for TCM810.
ELECTRICAL CHARACTERISTICS:
Vcc = Full Range, TA = Operating Temperature Range unless other-
wise noted. Typical values are at TA = +25
°C, VCC = 5V for L/M/J, 3.3V for T/S, 3.0V for R, and 2.5V for Z (Note 1).
