Function

Apply 4.0–5.5 V to Vcc, and 0V to Vss.

Reset internal shift register (built-in power-on reset

circuit).

Digit output varies according to rising edge of clock

input.

Use when specifying the number of digits.

Input “H” when using one M35501FP. Connect to

OVFOUT pin of additional M35501FPs when using

multiple M35501FPs (to use 17 digits or more).

Leave open when using one M35501FP. Connect to

OVFIN pin of additional M35501FPs when using multiple

M35501FPs (to use 17 digits or more).

Output the digit output waveform of fluorescent

display. Leave open when not in use (VEE level

output).

Apply voltage to DIG0–DIG15 pull-down resistors.
