One is that it has 8 lines in parallel. Each is paired and next to each other. But it will handle switching voltages up to 30volts and power up to 40ma.

Of course, if you really need power, the 2N remains even more useful. But, I really want to focus on the IC packaged devices. I personally feel the 74LS07 is a great protector of output pins and a good driver for LEDs, especially the newer, brighter ones. It can also easily adapt to driving relays and small motors. And with the 74LS06, one can invert logic so that states of output cannot possibly conflict.

So I wonder why it is often ignored? I suspect a lot of us overlook the meaning of 'open collector' when we are selecting chips. It is always sunny and warm here Tropically, G. PJAllen Banned Posts: 5, Either way, if you burn a gate you lose the whole package. Transistors cost least but they aren't in a DIP.

Beau Schwabe Posts: 6, Kramer, PJ's right Since the outputs are in 3-states, are they merely redundant or can be used creatively with a BasicStamp? On the one hand, I really thought the ULN was always more expensive due to added features.

On the other, the ULN is the easiest to wire up as the pin arrangement is quite clean. Chris Savage Parallax Engineering Posts: 14, Kramer, did you mean ULN? Actually, the ULN is the 7-output version we used to use. Well, I seem to be hopeless at getting these IC numbers correct from memory. Thank you for the correction because Googling the wrong number leads nowhere. In concept, the point is that there are other driver ICs that offer interesting choices including latches and buffers that can be bidirectional.

I am just try to figure out which contexts are useful to either protect the BasicStamp or to eliminate some of the more mundane work load. We mostly seem to expect the BasicStamp to do everything. Sign In or Register to comment.

They are also characterized for use as buffers for driving TTL inputs. These circuits are compatible with most TTL families. Inputs are diode-clamped to minimize transmission-line effects, which simplifies design. Typical power dissipation is mW, and average propagation delay time is 12 ns.
