The TC4404/TC4405 are CMOS buffer drivers with complementary MOS outputs and independent connections to the pull-up and pull-down sections of the output to allow the insertion of drain-current-limiting resistors. 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 allowing fast-OFF operation in motor-control applications.
The TC4404 and TC4405 are CMOS dual open‑drain MOSFET drivers with programmable rise and fall times, low output impedance and latch‑up protection. They are intended for motor‑control, bipolar transistor and MOSFET driving applications, offering fast switching (<30 ns) and the ability to limit base or drain currents.
The document provides electrical characteristics, pin descriptions, layout guidelines and typical application circuits, along with absolute maximum ratings and typical performance graphs.
| Supply Voltage Range | 4.5 V to 18 V |
|---|---|
| Rise Time (1000 pF load) | < 30 ns |
| Fall Time (1000 pF load) | < 30 ns |
| Peak Output Current (any drain) | 1.5 A |
| Latch‑Up Protection Current | > 500 mA |
The drivers operate from 4.5 V up to 18 V.
Both rise and fall times are less than 30 ns.
Each drain can withstand more than 500 mA of reverse current.
