8-bit bus transceiver for 5 V backplane and memory interfaces
The SN74ACT245NSR is an 8-bit non-inverting transceiver from TI's 74ACT family, packing eight bidirectional bus-interface channels with 3-state outputs into a 20-SOIC footprint.
Housed in a 20-SOIC (0.209", 5.30 mm width) with a supplier device package of 20-SO. The 1.27 mm pitch is a standard SOIC footprint that routes cleanly on two-layer boards.
Peer comparison — SN74ABT2245DW
The closest functional peer is the SN74ABT2245DW from the 74ABT series. Both are 8-bit non-inverting transceivers with 3-state outputs in a 20-pin SOIC package, operating over the same -40°C to +85°C range. The ABT variant delivers 32 mA output drive versus 24 mA on the ACT, giving it a small edge on heavily loaded buses. The ABT part ships in tube packaging rather than tape-and-reel, which may affect pick-and-place setup if your line is reel-fed.
