*Notice: Stresses above those listed under “Maximum ratings” may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at those or any other conditions
above those indicated in the operational listings of this specification is
not implied. Exposure to maximum rating conditions for extended peri-
ods may affect device reliability.

GND
Ground
RESET (TCM809) RESET push-pull output
remains low while VDD is below
the reset voltage threshold and
for 240 msec (140 msec min.)
after VDD rises above reset
threshold.
RESET (TCM810) RESET push-pull output
remains high while VDD is below
the reset voltage threshold and
for 240 msec (140 msec min.)
after VDD rises above reset
threshold.
VDD
Supply voltage (+2.5V, +3.0V,
+3.3V, +5.0V)
VDD = Full Range, TA = Operating Temperature Range, unless otherwise noted. Typical values are at TA = +25°C, VDD = 5V for L/M/J, 3.3V for T/S,
3.0V for R, and 2.5V for Z (Note 1).
