Product details

Bus transceiver for mixed-voltage backplanes

It provides 24 mA of source and sink drive per output, enough to handle a lightly loaded backplane or a handful of CMOS inputs on a shared data bus. The 3-state outputs let multiple transceivers share the same bus lines without contention.

The 1.65V to 3.6V supply range means this part works as a level translator between 1.8V and 3.3V logic domains without external level shifters. At 3.3V it is fully compatible with standard LVCMOS and LVTTL thresholds; at 1.8V it interfaces directly with low-voltage FPGAs or memory controllers. The 24 mA output drive at both voltage extremes keeps signal integrity on short traces up to a few inches.

Frequently asked questions

Is SN74ALVC245NSR compatible with 3.3V logic?

Yes, the 1.65V to 3.6V supply range includes 3.3V. At 3.3V the inputs and outputs meet LVCMOS and LVTTL thresholds, and the 24 mA drive is sufficient for typical 3.3V bus loads.
