Each output can sink or source 24 mA, enough to drive a terminated backplane trace or a bank of LEDs without an external line driver. The 3-state control lets multiple buffers share a common data bus — the outputs go high-impedance when the enable pins are deasserted. ## Industrial temperature and surface-mount footprint The 20-SOIC package (supplier device package 20-SOIC) uses a 1.27 mm pitch, standard for medium-density logic on 2-layer or 4-layer boards. The wide-body SOIC (0.295-inch body width) provides better thermal dissipation than the narrow version and matches the footprint of many octal bus-interface devices. Decoupling with a 0.1 µF ceramic close to each supply pin is recommended for the 5 V rail.","metaTitle":"SN74ACT244DWR Texas Instruments 74ACT Buffer, 5V, 24mA","metaDescription":"Active Texas Instruments SN74ACT244DWR buffer, non-inverting 3-state, 4.5V-5.5V supply, 24mA drive, industrial temp -40°C to 85°C.
