NAME
FUNCTION
Configure Input/IN7 Input. In serial mode (SRIAL = high), drive CNFG/IN7 high to enable per-

CNFG/IN7
channel configuration through the serial interface. In serial mode, drive CNFG/IN7 low to allow
setting the OUT_ outputs through the serial interface. In parallel mode (SRIAL = low), CNFG/IN7
sets OUT7 on/off/high/low.
16-Bit Serial Select/IN8 Input.
34
S16/IN8
In serial mode (SRIAL = high), drive S16/IN8 high to select 16-bit serial-interface operation.
Drive S16/IN8 low in serial mode for 8-bit serial operation.
In parallel mode (SRIAL = low), S16/IN8 sets OUT8 on/off/high/low.

Glitch Filter Enable Input. Set FLTR high to enable glitch filtering on all parallel logic inputs and
CS.
Open-Drain Fault Output. The FAULT transistor turns on low when a fault condition (driver
shutdown or open-load detect) occurs.
Push-Pull, High Slew-Rate Configuration Input. When PUSHPL is set high, all OUT_ pins
operate in push-pull mode. When PUSHPL is set low, all OUT_ pins operate in high-side mode.
Output Enable Input. Driving EN low turns all high-side OUT_ switches off, and three-states all
push-pull OUT_ drivers and turns all LED drivers off. Driving EN high enables normal operation.
