*1. For open collector (NPN) and CMOS level, COM (–). For open collector(PNP), COM (+).
*2. HOLD signal is for input, the others are for output.
*3. P0 corresponds to n × 100, P1 to n × 101, P2 to n × 102, P3 to n × 103. P0 – P3 are in sync when the parity for all digits
are valid.
*4. P0 corresponds to B0 – B3, P1 to B4 – B7, P2 to B8 – B11, P3 to B12 – B15. P0 – P3 are in sync when the parity for all
digits are valid.
Note: With the number of bits set to 14 (or 12, 10, 8) with ITEM 10, Pin No. 1 – 14 (or 1 – 12, 1 – 10, 1 – 8) are valid.
