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.
