BU2152FS
Description
BU2152FS is a CMOS output driver. It incorporates a
built-in shift register and a latch circuit to turn on a
maximum of 24 output by a 4-wire interface, linked to a
microcontroller.
A CMOS output can provides maximum 25mA current.

1. After the power is turned on and the voltage is stabilized, STB should be activated, after clocking 24 data bits
into the DATA terminal.
2. P1 to P24 parallel output data of the shift register is set after the 24th clock by the LCK.
3. Since the STB is a level trigger latch, data is retained in the “H” section and renewed in the “L” section of the
STB.
4. The final stage data of the shift register is outputted to the SO by synchronizing with the rise time of the CLK.

All the data of the latch circuit are set to “H” (data of shift register does not
change), all the parallel outputs are “H”.
H
Serial data of DATA pin are latched to the shift register.
At this time, the data of the latch circuit does not change.
The data of the shift register are transferred to the latch circuit, and the data of
H the latch circuit are outputted from the parallel output pin.
The data of the shift register shifts 1bit, and the data of the latch circuit and
parallel output also change.
