The TC4404/TC4405 are CMOS buffer-drivers
constructed with complementary MOS outputs, where
the drains of the totem-pole output have been left
separated so that individual connections can be made
to the pull-up and pull-down sections of the output. This
allows the insertion of drain-current-limiting resistors in
the pull-up and/or pull-down sections, allowing the user
to define the rates of rise and fall for a capacitive load.
It also enables a reduced output swing, if driving a
resistive load, or limiting base current when driving a
bipolar transistor. Minimum rise and fall times, with no
resistors, will be less than 30 ns for a 1000 pF load.
For driving MOSFETs in motor-control applications,
where slow-ON/fast-OFF operation is desired, these
devices are superior to the previously used technique
of adding a diode-resistor combination between the
driver output and the MOSFET, because they allow
accurate control of turn-on, while maintaining fast
turn-off and maximum noise immunity for an OFF
device.
When used to drive bipolar transistors, these drivers
maintain the high speeds common to other Microchip
drivers. They allow insertion of a base current-limiting
resistor, while providing a separate half-output for fast
turn-off. By proper positioning of the resistor, either
NPN or PNP transistors can be driven.
For driving many loads in low-power regimes, these
drivers require significantly less power at higher
frequencies and can be helpful in meeting low-power
budgets as they eliminate shoot-through currents in the
output stage.
