Strobe Signal Input

In case of “L”, the data of shift register is

outputted to P1 through P8.

In case of “H”, all parallel outputs and data of

latch circuit do not change.

CLR

I

Reset Signal Input

In case of “L”, the data of latch circuit reset,

and all parallel outputs(P1 to P8) change into

“L”.

Normally CLR=H

(Note 1) Mounted on 70mm x 70mm x 1.6mm glass epoxy board. Reduce 4.5mW per 1°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.
