Figure 3. Segment Connection for the MAX1367 (3.5 Digits)
The MAX1365/MAX1367 use a multiplexing scheme to
drive one digit at a time. The scan rate is fast enough to
make the digits appear to be lit. Figure 5 shows the

data-timing diagram for the MAX1365/MAX1367 where
T is the display scan period (typically around 1/512Hz
or 1.9531ms). T ON in Figure 5 denotes the amount of
time each digit is on and is calculated as follows:

Decimal-Point Control
The MAX1365/MAX1367 allow for full decimal-point
control and feature leading-zero suppression.

trol register to set the value of the decimal point (Tables
2 and 3). The MAX1365/MAX1367 overrange and
underrange display is shown in Table 4.
Leading-Zero Suppression
Table 4. LED During Overrange and
Underrange Conditions
The MAX1365/MAX1367 include a leading-zero sup-
pression circuitry to turn off unnecessary zeros. For
example, when DPSET1 and DPSET2 = [0,0], 0.0 is dis-
played instead of 000.0 (MAX1365). This feature saves

a substantial amount of power by not lighting unneces-
sary LEDs.
Interdigit Blanking
The MAX1365/MAX1367 also include an interdigit-
blanking circuitry. Without this feature, it is possible to
see a faint digit next to a digit that is completely on.
The interdigit-blanking circuitry prevents ghosting over
into the next digit for a short period of time. The typical
interdigit blanking time is 4μs.
