NOTES: 1. Over Entire Environmental Range.
2. Long term operation at the maximum junction temperature will result in reduced product life. Lower internal temperature by
reducing internal dissipation or using better heatsinking to achieve high MTTF.

INPUT
A logic level input independently controls each FET in
the half bridge. A logic level high turns on the FET and
However, input impedance is 50k on all inputs; therefore if
one input is open circuited a high radiated noise level could
spuriously turn on a FET.

FETs when high.
All inputs are Schmitt triggers with the upper threshold at

interfaces with CMOS or HCMOS provided that the Vdd for
the logic family and the EB03 are the same.
TTL families may be used if a pull-up to Vcc is added to
the TTL gates driving the EB03, and Vdd for the EB03 is the
same supply as V
An open signal connector pulls the shut down input high

OUTPUT
Each output section consists of a switching mode FET half
bridge. Separate HV supply, emitter, and HV return lines are
provided for each section.
The FETs are conservatively rated to carry 5A. At 5A the
saturation voltage is 1.9V maximum.
Each FET has an intrinsic diode connected in anti-parallel.
When switching an inductive load this diode will conduct, and
the drop at 5A will be 1.9V maximum.
and all other inputs low, insuring that all outputs are off.
