PSPICE, beginner's question

I am new to PSPICE, I only need help in schematic/layout, not analysis. I can draw basic, RLC circuits. I want to draw a circuit containing ULN2003 chip. I cannot find this chip in any of the component libraries. Is there a component for a generic 16 pin chip, I can use that and add the text myself....

How to use a relay in a breadboard.

I want to use a relay NAIS, HX2-4.5-H12 in a bread board. But relay pins are completely incompatible with breadboard holes.

Is this a common problem?

Is there a standard solution?

Thanks in advance.

I agree with bigglez's view on function of internal diodes. I have seen similar diodes in ULN2003 chips and they work fine. I am trying to understand this back emf, voltage spike, thing. I dont think I fully understand it yet. I am trying to do the transient analysis of a simple LR circuit and see t...

Vcc & Vdd on the same chip (LB1205)

Hi, I want to use LB1205 (high current/voltage darlington drivers), in one of my projects. Normally, I am familiar with seeing only one supply voltage in a chip (Vcc or Vdd). But on LB1205, I see both . Vcc on pin 1, 7 Vdd on pin 10. According to data sheet Vcc max is 62 Vots & Vdd max is 7 volts. I...
