Specifically, I am looking for a pin-compatible replacement for
an F245 octal transceiver.

Requirements are:

	B bus must handle 64 mA
	A bus must handle 20 mA
	B bus has low (~3 V) voltage swing
	prop delay of 7 ns, max.

As you may have guessed, I need this part to reduce noise
on a backplane by reducing the voltage swing of the backplane
signals.  The other possibility of reducing the noise is to
slow the edge rate.  Are there transceivers with edge rate 
(slew rate) control, pin-compatible with the 245?

Any info is greatly appreciated.

thanks

tracy
