Use a quad two input XOR (74HC86 or similar) gate package -- use=
 two
gates, connect your input signal to one input of each gate.=
 Connect a
logic '1' (+V) to the other pin of one gate and logic '0'=
 (ground) to
the other pin of the second gate.

You now have an inverted signal on the output of gate with a=
 logic '1'
on the input and a non-inverted signal on the output of the gate=
 with a
logic '0' on the input.

The delay will be the same (or very very close) for both signals.=
 XOR
gates make great switchable inverters, dirt cheap too! ;-)
