General Purpose CMOS Logic IC
8bit Static Shift/Store Register
BU4094BC BU4094BCF BU4094BCFV
General Description
The BU4094BC/BCF/BCFV are shift/store register
composed of 8 bit shift register and 8 bit latch. The read
data in the shift register can be taken in the latch through
the asynchronous strobe input; therefore, the data
transfer mode can hold output.

(Note 1) Reduce 10mW/°C above 25°C.
(Note 2) Mounted on 70mm x 70mm x 1.6mm glass epoxy board. Reduce 5mW /°C above 25°C.
(Note 3) Mounted on 70mm x 70mm x 1.6mm glass epoxy board. Reduce 7mW /°C above 25°C.
Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins
or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such
as adding a fuse, in case the IC is operated over the absolute maximum ratings.
