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.
