*Notice: Stresses beyond those listed under “Absolute Maximun Rat-

ings” may cause permanenet damage to the device. These are stress

ratings only, and functional operation of the device at these or any other

conditions beyond those indicated in the operational sections of the

specifications is not implied. Exposure to absolute maximun rating con-

ditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS

NAME

FUNCTION

GND

Ground

RESET (TCM811)

RESET push-pull output remains low

while

DD is below the reset voltage

threshold, and for at least 140 msec

(min.) after

DD rises above reset

threshold.

RESET (TCM812)

RESET push-pull output remains

high while

DD is below the reset

voltage threshold, and for at least

140 msec (min.) after

DD rises

above reset threshold.

Manual Reset input generates a

reset when MR is below VIL.

Supply Voltage

DD = 5V for L/M versions, VDD = 3.3V for T/S versions, VDD = 3V for R version, VDD = 2.0V for F version.

TA = –40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C. (Note 1)
