Tested with V+ = 5.5V (and V- = 0V for MAX909). MAX909 also tested over the full analog input range (i.e., with
V- = -5.5V).
Tested over the full input voltage range (V
Specified over the full tolerance of operating supply voltage: MAX907/MAX908 tested with 4.5V < V+ < 5.5V. MAX909
tested with 4.5V < V+ < 5.5V and with -5.5V < V- < 0V.
Positive Supply Current specified with the worst-case condition of all outputs at logic low (MAX907/MAX908), and
with V+ = 5.5V.
Typical power specified with V+ = 5V; maximum with V+ = 5.5V (and with V- = -5.5V for MAX909).
Due to difficulties in measuring propagation delay with 5mV of overdrive in automatic test equipment, this parameter is
guaranteed by design for the MAX907 and MAX908. Correlation tests show that the specification can be guaranteed if all
other DC parameters are within the specified limits. V
For the MAX909, propagation delay is typical only and there is no guaranteed maximum limit.
