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. V ee 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 V ee so that the negative
output current varies directly with V ee.
