GENERAL DESCRIPTION
The TC4404 and 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; or a reduced output swing, if
driving a resistive load, or to limit base current, when
driving a bipolar transistor. Minimum rise and fall times,
with no resistors, will be less than 30 nsec for a 1000-pF
load. There is no upper limit.
For driving MOSFETs in motor-control applications,
where slow-ON/fast-OFF operation is desired, these de-
vices are superior to the previously-used technique of add-
ing 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 TelCom driv-
ers. 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 transis-
tors can be driven.
For driving many loads in low-power regimes, these
drivers, because they eliminate shoot-through currents in
the output stage, require significantly less power at higher
frequencies, and can be helpful in meeting low-power
budgets.
Because neither drain in an output is dependent on
the other, these devices can also be used as open-drain
buffer/drivers where both drains are available in one device,
