SERIAL DATA present at the input is transferred to the shift register on the logic “ 0 ” to logic “ 1 ” transition of the CLOCK input
pulse. On succeeding CLOCK pulses, the registers shift data information towards the SERIAL DATA OUTPUT. The SERIAL
DATA must appear at the input prior to the rising edge of the CLOCK input waveform. Holding CLEAR high results in a data
logic "0" being clocked into the shift register, turning off respective channels.
Information present at any register is transferred to its respective latch when the STROBE is high (serial-to-parallel conversion).
The latches will continue to accept new data as long as the STROBE is held high. Applications where the latches are bypassed
(STROBE tied high) will require that the ENABLE input be high to prevent invalid output states.
When the ENABLE input is high, all of the output buffers are disabled (OFF) without affecting information stored in the latches
or shift register. With the ENABLE input low, the outputs are controlled by the state of the latches. A positive OE/RESET pulse
resets the FLAG and the output after a current shutdown fault. Over-temperature faults are not latched and require no reset
pulse.
