Applications
V
CC
Bias Voltage vs R
ON
To keep R
ON
to a minimum, it is recommended that the V
CC
voltage
be increased to a voltage between +6.0V and +6.5V (see Figure 5).
The R
ON
vs V
IN
curve shows the effect of ON-resistance and
input voltage which is exponential. Ideally an input voltage
between 0.2V and 3.6V will keep R
ON
in the flat part of the curve
(
R
ON
or flatness is ~2ohm).
Logic Inputs
The logic control inputs can be driven up to +5.5V regardless of
the supply voltage. For example, given a +5.0V supply, E may be
driven low to 0V and high to 5.5V. Driving E Rail-to-Rail
minimizes power consumption.
Power-Supply Sequencing
Proper power-supply sequencing is recommended for all CMOS
devices. Always apply V
CC
before applying signals to the input/
output or control pins.
