† 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.

NAME

FUNCTION

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).

ELECTRICAL CHARACTERISTICS

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).
