LV5232VH no.a1628-4/8 block diagram function the LV5232VH consists of 1) an 16-stage d-type flip-flop a nd 2) an 16-stage d-type flip-flop connected to the output of 1). when data is supplied to the serial data input (s datain) and the clock pulse is supplied to the clock input (sck), the serial data input si gnal 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 led01, and the output is shifted sequentially. for parallel output s (led2 to led16), the signals whose polarities inverted from those of the serial data input (sdatain) are output. when the en input is high, outputs led01 through led01 all turn off. when the reset input is low, outputs led01 through led16 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 v cc . xreset sv cc xen sout sgnd pgnd1 pgnd2 latch sdatain sck ledo1 dq c r q dq c r q dq c r q dq c r q dq c r q dq c r q dq c r q dq c r q dq c r q dq c r q dq c r q dq c r q dq c r q ledo2 ledo3 ledo14 ledo15 ledo16 sv cc _protection pgnd3 pgnd4 ledo4 ledo13
