Circuit operation

•

The BA829 has the internal configuration shown in the

logic diagram, with the following five input pins: clock

(CLK), data (DATA), latch (LATCH), strobe (STB), and

power switch (PSW).

being the same as that of the strobe input.

The data output pin DOUT is used when ICs are con-

nected in cascade format, and when the output for the

last stage of the shift register appears, is connected to

the next data input pin DATA.

Data input is synchronized to the clock, with data being

read serially at the rising edge and latched at the rising

edge of the shift register after it has shifted. The

latched data appears at output terminals O¹to O8,

depending on the strobe input, with that pulse width

When these clock and strobe latches and power switch

are used in common, the output pins can be increased

by eight bits each.

In stand-by mode, the power switch is set to “L”.
