Monolithic High-Speed Pin Driver
Applications Information
Contd
load currents must be limited to 60 mA Short-
circuits can rapidly destroy the EL1056 although
the part will survive for 20 ms periods If there is
the possibility of output load fault the overcur-
rent sense circuitry should be used to signal
alarm to the controlling system which should ul-
timately activate the tristate mode to relieve the
output stage Driving large static currents also
raises internal dissipation and should be part of
the thermal budget
The collectors of the output transistors are con-
nected to the Shunt terminals and the output
stage drivers’ collectors are connected to the Ba
and Bb terminals (see Figure 4) The Shunt
lines can have transient currents as high as
120 mA and are separated from the Va and Vb
terminals to keep switching noise out of the con-
trol and logic circuitry
A bypass capacitor
should be connected to the Ba and Bb termi-
nals
