LV5232VH
Function
The LV5232VH consists of 1) an 16-stage D-type flip-flop and 2) an 16-stage D-type flip-flop connected to the output
of 1). When data is supplied to the serial data input (SDATAIN) and the clock pulse is supplied to the clock input
(SCK), the serial data input signal is input to the internal shift register and the data already in the shift register shifted
sequentially when the clock changes from low to high.
The serial output (SOUT) is used to connect multiple LV5232VH to expand the number of bits and is connected to the
SDATAIN of the next stage. (Cascade connection supported.)
For parallel output, when the output control enable input (XEN) is low, the latch input (LATCH) changes from low to
high and the clock pulse input changes from low to high, the serial data input signal is output to LEDO1, and the output
is shifted sequentially. For parallel outputs (LEDO2 to LEDO16), the signals whose polarities inverted from those of
the serial data input (SDATAIN) are output.
When the EN input is high, outputs LEDO1 through LEDO16 all turn off.
When the reset input is low, outputs LEDO1 through LEDO16 and SOUT outputs all turn off. The power must be
turned on after checking that the reset input is low.
To prevent the malfunction, the output load protection circuit is built into. The output of LEDO1 to LEDO16 is
compulsorily turned off when becoming below the voltage with a constant there is VCC.
