... L = 4.63V 4.38V 3.08V 2.93V, and R = 2.63V. All three devices have an active-low reset output, which is guaranteed the correct state for V down to 1V. The MAX824/MAX825 also CC have an active-high reset output. The following Selector Guide explains the functions offered in this series of parts. ...

... The RESET output maximum pull-up current is 800µA for L/M versions (400µA for T/S/R versions). This allows µPs with bidirectional resets, such as the 68HC11, to force RESET low when the MAX823/MAX824/MAX825 are pulling RESET high (Figure 4). Negative-Going V These supervisors are relatively immune to short- ...
