STP04CM05 - 4-bit LED array driver

previous status if the junction temperature falls, typically 15-20 °C, below the thermal
shutdown threshold.

Figure 4 shows a typical timing diagram of a 4-bit LED driver.
The LE pulse latches the last 4 bits loaded into the shift register through the SDI pin and
sampled by the last 4 clock rising edges.
As long as the
pin is high, all current generators are not active. Once
is set low, the
current generators are enabled and their status is determined by the data latched by the last
LE pulse.
