consumption. When either of the two signals is pulled LOW,
an active pull-up current of 275µA maintains a good V
noise margin.
When the bus line is released, it is pulled high by the
ISL54103 active current until the voltage exceeds the
V
combination filters out noise on the signal line. Once the
ISL54103 detects a valid rising edge, a 2.2mA boost current
pulls the bus line high very quickly (see Figure 8). This boost
current turns off when the input level reaches the V
threshold and the pull-up current returns to the active level. If
both inputs are HIGH, the pull-up current drops to the
standby level of 100µA.
