F IVE & SIX C HANNEL HIGH SPEED DRIVERS DDF5311 DDF6311 Independent high speed drivers with 300 mA peak current spikes. 1. Inputs are non-inverting when Mode control has a logic high input. 2. Inputs are inverting when Mode control has a logic low input. 3. To increase switching spike currents, add a capacitor of up to 560 pF between the output and TP pins. 4. Mode control and input pins are interchangeable within any one channel. 5. When driving anode-grounded diodes, excessive power dissipation must be avoided. Vgg should be limited to -8 V with -5 V recommended. 6. These drivers do not have a true current source output. Instead the output is connected to a 380-ohm resistor in parallel with a 560 pF capacitor and the driven end of this RC combination is switched between +4 V and Vee so that the negative output current varies directly with Vee.
