Independent high speed drivers with 300 mA peakcurrent spikes.

1. Inputs are non-inverting when Mode control has alogic high input.

2. Inputs are inverting when Mode control has a logiclow input.

3. To increase switching spike currents, add a capacitorof up to 560 pF between the output and TP pins.

4. Mode control and input pins are interchangeablewithin any one channel.

5. When driving anode-grounded diodes, excessivepower dissipation must be avoided. Vgg shouldbe limited to -8 V with -5 V recommended.

6. These drivers do not have a true current sourceoutput. Instead the output is connected to a 380-ohmresistor in parallel with a 560 pF capacitor and thedriven end of this RC combination is switchedbetween +4 V and Vee so that the negative outputcurrent varies directly with Vee.
