TC4404/TC4405
1.5A Dual Open-Drain MOSFET Drivers
Features General Description 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. Independently Programmable Rise and Fall Times
Low Output Impedance: 7пЃ— Typical
High Speed tR, tF: <30 ns with 1000 pF Load
Short Delay Times: <30 ns
Wide Operating Range: 4.5V to 18V
Latch-Up Protected: withstands > 500 mA
Reverse Current (Either Polarity) Input Withstands Negative Swings up to -5V Applications Motor Controls
