_______________________________________________________________________________________
For a large differential input voltage (exceeding 3V
F
),
this protection circuitry increases the input bias current
at IN+ (source) and IN- (sink).
(IN+ - IN-) - 3V
F
2 x 200
Input current = ————————
Input currents with large differential input voltages
should not be confused with input bias currents (I
B
).
As long as the differential input voltage is less than
3V
F
, this input current is less than 2I
B
.
The input circuitry allows the MAX961–MAX964/
MAX997/MAX999’s input common-mode range to
extend 100mV beyond both power-supply rails. The
output remains in the correct logic state if one or both
inputs are within the common-mode range. Taking
either input outside the common-mode range causes
the input to saturate and the propagation delay to
increase.
