FUNCTIONAL DESCRIPTION

The CAT310 implements a 10-bit serial-in shift

Serial input data SIN are clocked into the shift

10th clock pulse, the first data bit entered is

outputted from the shift register to SOUT. The

following clock pulses will output the following

data bits onto SOUT. The output data pattern

replicates the input data stream with a delay of

ten clock pulses.

The 10-bit data pattern present in the shift

the latch signal XLAT is logic high. When XLAT

transitions to logic low, data are latched and

stay unchanged for as long as XLAT remains

low. The last serial input data corresponds to

OUT0. The serial input data that was received

10 clock pulse ago is stored in OUT9. When the

BLANK input is logic high, all the output

switches are in the off state. If the BLANK input

is low, the 10-bit data latches control the 10

output switches. A data bit value of zero keeps

the switch off. A data bit value of one keeps the

switch on.
