DD311A
DD311A M *
Ultra High Speed SPST
A n inverting only ultra high speed driver with
300 mA switching current spikes. The DD311A
output (pin 2) is connected to a 360 ohm resistor
paralleled with a 560 pF capacitor and the driven
end (pin 11) of the resistor/capacitor combination
is switched between +4 and -10 V.
1. The DD311A should be driven from an otherwise
unloaded 54S, 54A S, or 54F type gate to achieve
rated switching times. Input capacitance is ap-
proximately 50 pF.
2. To increase switching peak currents, add a capaci-
tor of up to 560 pF between the output and TP pin.
* M suffix denotes welded metal package instead of standard epoxy-sealed
ceramic package.

High Speed Drivers
Single channel 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 logic
low input.
3. To increase switching peak currents, add a capaci-
tor of up to 560 pF between the output and TP pin.
4. M ode control and input pins are interchangeable
within any one channel.
5. D DF311 Series 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 and V ee so that the negative
output current varies directly with V ee.
