INH/FLT Characteristics
Maximum ratings:
FLT Terminals:
INH Terminals:
16.5 Vdc between terminals 1 and 2; 3 and 4; and
from terminals 1 or 2 to chassis ground
Low-level output current = 1.25 mA max.
Low-level output voltage = 0.5 V max.
Low-level input voltage = 0.8 V max.
High-level input voltage = 2 V min.
Low-level input current = 1 mA

Digital I/O Characteristics
Maximum ratings:
Digital OUT Port 0,1,2
(open collector)
Digital IN Port 2:
(internal pull-up)
same as INH/FLT Characteristics
Output leakage @ 16V = 0.1 mA (ports 0,1)
= 12.5 mA (port 2)
Output leakage @ 5V = 0.1 mA (ports 0,1)
= 0.25 mA (port 2)
Low-level output sink current @ 0.5 V = 4 mA
Low-level output sink current @ 1 V = 50 mA
Low-level input current @ 0.4 V = 1.25 mA
High-level input current @ 5 V = 0.25 mA
Low-level input voltage = 0.8 V max.
High level input voltage = 2.0 V min.

COMPatibility language is used to program the Agilent 663xA Series power supplies. Not all Agilent 66111A/66311B
capabilities are available when using the COMPatibility language.
