Direct control mode (DCM)

When SYNC

and LOAD

inputs are driven by the same signal, the device operates in

direct control mode (DCM).

In DCM the SYNC / LOAD

signal operates as an active low input enable:



when the signal is high, the current output configuration is kept regardless the input

values



when the signal is low, each channel input directly drives the respective output

This operation mode can also be set shorting both signals to the digital ground; in this case

the channel outputs are always directly driven by the inputs except when OUT_EN is low

(outputs disabled).

Device behavior

Don’t care

Low (1)

The outputs are disabled (turned off)

High

The outputs are left unchanged

Low

High

The channel inputs drive the outputs

Notes:

(1)The outputs are turned off on OUT_EN falling edge and they are kept disabled as long as it is low.
