The following schemes depict one of the BCD outputs in positive and negative logic respectively.
Positive logic
Negative logic
The TRISTATE input is triggered externally and is always active at level "
1
".
In positive logic the signals are active at
level "
1
" and negative at level "
0
".
The POLARITY is positive (+), if the bit is on
a high level and negative (-), if it is on a low
level with respect to GND.
The MEASUREMENT VALUE OVER-
SHOOT is positive, if the bit is on a high level
and negative, if it is on a low level. When
there is measurement value overshoot, the
four lowest digits (D0, D1, D2 und D3) are
FFFF.
Parameters of the output transistors:
Vmax = 40 V Imax = 100 mA
