data. Holding OE low allows the output channels to fol-
low the state of the output latches. The duty cycle
depends on LE’s frequency. All output channels are
affected at the same time.

Another method of pulse dimming the outputs is to hold
LE high and drive OE with a PWM signal. Because the
input bits are always latched, the serial input constantly
refreshes the register. The control bits must be carefully
selected to dim the outputs properly.
