Freescale Semiconductor Advance Information 16 Output Switch with SPI Control The 33996 is a 16-output low side switch with a 24-bit serial input control.

It is designed for a variety of applications including inductive, incandescent, and LED loads.

The Serial Peripheral Interface (SPI) provides both input control and diagnostic readout.

A Pulse Width Modulation (PWM) control input is provided for pulse width modulation of multiple outputs at the same duty cycle.

A dedicated reset input provides
