[Test-Equipment] Need to shift pulse up 5V

[Barry]

I have a situation where a clock signal is pulsed to 0V from a normally -5V signal level.  I would like to have that same waveform shifted +5V (e.g. the pulse would go from 0V to +5V instead of -5V to 0V).

Is there a convenient way to do this?  I thought this might be a somewhat common problem and there would be a selection of "level shifting" chips but I'm not finding that to be true.  I assume that if there's no dedicated IC for this kind of thing, then perhaps a simple single transistor circuit might do the trick but thought I'd ask first if there are any off-the-shelf "standard" solutions to this.

Thanks,
