National Semiconductor DH3467C
The DH3467C consists of four 2N3467 type PNP transistors mounted in a 14-pm molded dual-m-line package. The device is primarily intended for core memory application requiring operating currents in the ampere range, high stand-off voltage, and fast turn-on and turn-off times.Memory/Clock Drivers DH3467C quad PNP core driver general description typical characteristics Turn-ON Time Turn-OFF Time Collector Current Collector-Base Breakdown Voltage Collector Saturation Vbltage at Ie = 1A Collector Saturation Voltage at Ie = O.5A 18 ns 45 ns 1A 120V typo O.55V O.31V connection diagram Dual-I n-Line Package Order Number DH3467CD See Package 1 Order Number DH3467CN NC See Package 22 TOP VIEW -JOV ,gn 200.11 SCOPE lNDI6 .,v t3<IJ.iS DUTY CYCLE" 2% FIGURE 1.
