EL1056AC EL1056C

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
