Description
Driver Output.
Wide voltage differential input digital pins which determine the driver high or
low level.
Wide voltage differential input digital pins which control the driver being active
or in a high impedance state.
High impedance analog voltage inputs which determine the driver high and low
level.
Op amp compensation pin. A 100 pF capacitor should be connected to DVH.

Input currents which determine the driver transition times.
Analog current input which sets an internal bias current.
TTL driver input power down control which slows the driver down and reduces
the driver HiZ leakage current.

Analog voltage input to the positive input of comparators.
Analog inputs which set the comparator thresholds.
Differential ECL (or PECL) digital outputs of comparators A and B.
TTL input power down input which slows the comparator down, but
significantly reduces the VINP bias current.
Unbuffered power supply level for the comparator output stages which
establishes either ECL or PECL digital levels.

Load Output.
Wide voltage differential inputs which activate and disable the load.
High impedance analog voltage input that programs the commutating voltage.
Analog current inputs which program the load source and sink currents.
Should be connected to external voltage or current source through minimum
500 Ω series resistors.
Commutating buffer op amp compensation pin.
Commutating voltage pins.
Diode bridge connections to the output bridge that bypass the internal current
sources.
