33879 Datasheet Configurable octal serial switch

Manufacturer: NXP Semiconductors

Overview

NXP Semiconductors Technical Data Configurable octal serial switch with open load detect current disable The 33879 device is an 8-output hardware configurable, high-side/low-side switch with 16-bit serial input control using the serial peripheral interface (SPI).

Two of the outputs may be controlled directly via a microcontroller for pulsewidth modulation (PWM) applications.

The 33879 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs.
