Octal, High-Speed, Industrial, High-Side Switch
8-Bit Serial Mode with Setting and Monitoring
In serial mode with 8-bit setting and 8-bit monitoring
(SRIAL = high, S16/IN8 = low, CNFG/IN7 = low), the SPI
shift register is 8 bits long (Figure 7). The DO_ bits set
the state of the respective O_ output (Table 4). The F_
bits report fault information of the respective O_ output
(Table 7).
8-Bit Serial Mode with Configuration and
Monitoring
In serial mode with 8-bit configuration and 8-bit monitor-
ing (SRIAL = high, S16/IN8 = low, CNFG/IN7 = high), the
SPI shift register is 8 bits long (Figure 8). The C_ bits
configure push-pull/high-side mode for the respective O_
output (Table 5). The F_ bits report fault information for
the respective O_ output (Table 7).
