APPLICATIONS
Because of this diode, V
Lastly, the maximum voltage between any two power
supply pins must not exceed 15V operating or 18V abso-
lute maximum. For example, if V
be no more negative than – 10V. Note that V
be more negative than – 10V even if the V
differential does not exceed the 15V maximum. In this
case the V
Input Voltage
The LTC1045 has no upper clamp diodes as do conven-
tional CMOS circuits. This allows the inputs to exceed the

under these conditions (i.e., if the input voltage is above
the trip point, the output will be high and if it is below, the
output will be low).
Output Drive
Output drive characteristics of the LTC1045 will vary with
the power supply voltages that are chosen. Output imped-
ance is affected by V
output impedance. Guaranteed drive characteristics are
specified in the table of electrical characteristics for
V
relative output impedance for other supply combinations.
In general, output impedance is minimized if V
