Technical Data

Eight Output Switch with Serial

Peripheral Interface I/O

33298

The 33298 is a smart eight output low side power switch. It is a

versatile device incorporating an 8-bit serial-in shift register to control

an 8-bit parallel output latch providing control of eight independent

"ON/OFF" output switches. Applications include the control of

solenoids, relays, lamps, small DC motors, and other moderate current

loads (1.0 – 3.0A).

LOW SIDE SWITCH

The 33298 interfaces directly with a microcontroller to control

various inductive or incandescent loads. Input control is fast. Data

rates are guaranteed to 2.0 MHz but the device is capable of rates to

8.5 MHz @ 25°C.

Each output uses high efficiency MOSFET power transistors

configured with open drains. Each low "ON" resistance output (0.4Ω

R_DS(ON)@ 25°C) is capable of sinking up to 3.0A of transient current.

On a continuous basis, each output can simultaneously (with all

outputs "ON") handle 0.5A of current when the device is soldered onto

a typical PC board. Higher output currents are dependent on the

number of outputs simultaneously "ON". The circuit's innovative

monitoring and protection features include very low standby current.
