4 / 6 page DDF2311 DDF3311 DDF4311 Tw o, Three, and Four Channel High Speed Drivers M ultiple independent high-speed drivers w ith 300 mA peak current spikes. 1. Inputs are non-inverting w hen M ode control has a logic high input. 2. Inputs are inverting w hen M ode control has a logic low input. 3. To increase sw itching spike currents, add a capacitor of up to 560 pF betw een the output and TP pins. 4. M ode control and input pins are interchangeable w ithin any one channel. 5. W hen driving anode-grounded diodes, excessive pow er dissipation must be avoided. V ee should be limited to -8V w ith -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 w ith a 560 pF capacitor and the driven end of this RC combination is sw itched betw een +4V and V ee so that the negative output current varies directly w ith V ee.
