2N7001T: How fast can this run? Can it really drive 50mA?

Ron Breding

Part Number: 2N7001T

I would like to run up to 100Mbps and drive a 50 Ohm load powered at 3.3V preferably 1.8V. The data sheet shows a typical input slew rate of 100ns/V which seems quite contradictory to the operational bit rate advertised. The plots also seem to show an output current limitation of +/-12mA at 3.3V on the output buffer or +/-8mA at 1.8V on the output buffer. I want to level shift a 100MHz 1.8V signal to 3.3V and drive a 50 Ohm receiver. Is this IC capable of this or do I need to redesign.

Hey Ron,

The input transition rate limits the how slow the edges of your input signal can be, it doesn't necessarily correlate to operation frequency of the device. Unfortunately, this device would not be able to drive a 50 ohm load @ 3.3 V. We don't really have a translation device that can handle that amount of current.

Thanks. This clears up quite a bit. Thank you for your help
