circuitry is also provided. This is activated if

the watchdog input has not been toggled

APPLICATIONS

The CBM705 and CBM706 are identical

except for the reset threshold monitor levels,

which are 4.65V and 4.40V, respectively.

The CBM707 and CBM708 provide a

similar functionality to the CBM705 and

CBM706 and only differ in that a watchdog

timer function is not available. Instead, an

active high reset output (RESET) is available as

well as the active low reset output ( RESET ).

The CBM707 and CBM708 are identical except

for the reset threshold monitor levels, which

are 4.65V and 4.40V, respectively.

All devices are available in narrow 8-lead

SOIC packages.
