Electrical Characteristics (Cont’d): (Note 2, unless otherwise specified, all specifications apply
with the following conditions:
3VDC ≤ V+ ≤ 20VDC
3VDC ≤ VLED ≤ V+
–0.015V ≤ VRLO ≤ 12VDC
–0.015V ≤ VRHI ≤ 12VDC
VREF, VRHI, VRLO ≤ (V+ –1.5V)
0V ≤ VIN ≤ V+ –1.5V
TA +25°C, IL(REF) = 0.2mA,
VLED = 3V, Pin9 connected to Pin3

Note 2. Pin5 input current must be limited to ±3mA. The addition of a 39kΩ resistor in series with
Pin5 allows ±100V signals without damage.
Note 4. Bar mode results when Pin9 is within 20mV of V+. Dot mode results when Pin9 is pulled at
least 200mV below V+ or left open circuit. LED No. 10 (Pin10 output current) is disabled if
Pin9 is pulled 0.9V or more below VLED.

Note 3. Accuracy is measured referred to +10.000VDC at Pin5, with + 10.000VDC at Pin6, and
0.000VDC at Pin4. At lower full–scale voltages, buffer and comparator offset voltage may
add significant error. See table for threshold voltages.
