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.","metaTitle":"SN74ACT245NSR 8-bit transceiver, 24mA, 20-SOIC","metaDescription":"TI SN74ACT245NSR 8-bit non-inverting transceiver, 3-state outputs, 24mA drive, 4.5-5.5V, -40 to 85°C, 20-SOIC.
