3.12 M35501FP

USAGE

Three usages of the M35501FP are described below.

(1) 16-Digit Mode: 16 digits selected

The number of digits is set to 16 by fixing the OVFIN pin to “H” and

the SEL pin to “L.” Figure 3.12.5 shows the output waveform.

(2) Optional Digit Mode: 1-16 digits selectable

When the number of CLK pin rising edges during an “H” period of

the SEL pin is n and the OVFIN pin is fixed to “H,” the number of

digits set is n. If n is 16 or more, all 16 digits are set. Figure 3.12.6

shows the output waveform.

(3) Cascade Mode: 17 digits or more selectable

17 digits or more can be used by connecting two M35501FPs or

more. Figure 3.12.7 shows an example using three M35501FPs, of-

fering 33 to 48 digit outputs.

Cascade mode will not operate if all M35501FPs are in 16-digit

mode (SEL = “L”). Use the most significant M35501FP in the optional

digit mode for DIG output. Figure 3.12.8 shows the output waveform.
