5 / 6 page DD311A DD311A M * Ultra High Speed SPST A n inverting only ultra high speed driver w ith 300 mA sw itching current spikes. The DD311A output (pin 2) is connected to a 360 ohm resistor paralleled w ith a 560 pF capacitor and the driven end (pin 11) of the resistor/capacitor combination is sw itched betw een +4 and -10 V. 1. The DD311A should be driven f rom an otherw ise unloaded 54S, 54A S, or 54F type gate to achieve rated sw itching times. Input capacitance is ap- proximately 50 pF. 2. To increase sw itching peak currents, add a capaci- tor of up to 560 pF betw een the output and TP pin. * M suf f ix denotes w elded metal package instead of standard epoxy-sealed ceramic package.

Inputs are non-inverting w hen M ode control has a logic high input. 2. Inputs are inverting w hen M ode control has logic low input. 3. To increase sw itching peak currents, add a capaci- tor of up to 560 pF betw een the output and TP pin. 4. M ode control and input pins are interchangeable w ithin 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 w ith a 560 pF capacitor and the driven end of this RC combination is sw itched betw een +4 and V ee so that the negative output current varies directly w ith V ee. * M suf f ix denotes w elded metal package instead of standard epoxy-sealed ceramic package.
