DDF3311(V2) Datasheet PDF - API Technologies Corp

 2-, 3- & 4-CHANNEL HIGH SPEED DRIVERS

M ultiple independent high-speed drivers with 300 mA peak current spikes.
1. Inputs are non-inverting when M ode control has a
   logic high input.
2. Inputs are inverting when M ode 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. M ode control and input pins are interchangeable
   within any one channel.
5. W hen driving anode-grounded diodes, excessive
   power dissipation must be avoided. Vee should be
   limited to -8V with -5V recommended.
6. The DDF2311/3311/4311 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 +4V and Vee so that the negative
   output current varies directly with Vee.
