I was testing the ULN2803 mentioned in another thread, and
was amazed at how fast this chip is. I drove a 130 mA load
30 ohm resistor [5v - Vcesat(=1v)] at 2 mhz. Nice and clean.

For those not familiar, the 2803 chip is an 8-channel darlington
driver, rated at nominal 0.25usec turn-on/turn-off delays [ala
50-50 points] --> and it actually does this under load.

Anyone else have experience using these chips at high-frequencies
under load? I thought darlingtons were supposed to be slow.
