Product details

8-bit bus transceiver with 24 mA drive

The Texas Instruments 74ACT11478DW is an 8-bit non-inverting transceiver with 3-state outputs, part of the 74ACT logic family.

How it compares to SN74ABT2245DW

The closest functional peer is the SN74ABT2245DW — also an 8-bit non-inverting transceiver with 3-state outputs in the same 28-SOIC package. The ABT part pushes 32 mA output drive (vs 24 mA on the ACT) and runs from a 4.5 V supply minimum. If your BOM needs the extra drive margin and can tolerate the slightly tighter supply floor, the ABT2245 is a drop-in replacement on the same footprint.

Frequently asked questions

What is the closest functional second-source for 74ACT11478DW?

The SN74ABT2245DW is the closest functional peer — same 8-bit non-inverting transceiver, same 28-SOIC package, same 3-state outputs. The ABT part offers 32 mA output drive versus 24 mA on the ACT, and its minimum supply is 4.5 V. It is a drop-in replacement on the same footprint.
