The Texas Instruments SN74LVC244APWR is an octal buffer and line driver with 3-state outputs, supplied in a 20-pin TSSOP package. It operates from a 1.65 V to 3.6 V supply, drives eight non-inverting channels at plus or minus 24 mA, and delivers roughly 5.7 ns propagation delay with 1 microamp quiescent current. The SN74LVC244APWR is organized as two 4-bit elements with independent output-enable control and is rated for -40°C to 125°C.

Octal buffers with 3-state outputs are used to drive address, data, and control buses, to isolate a bus segment when a device is not selected, and to restore signal integrity on long or heavily loaded traces. The 24 mA drive lets one device fan out to several loads or drive a backplane, while the 3-state capability lets multiple sources share one bus. A 1.65 V to 3.6 V range covers 1.8 V, 2.5 V, and 3.3 V logic families, making the SN74LVC244APWR a common bus-interface part in networking gear, industrial controllers, storage, and instrumentation. Hardware engineers and OEM buyers keep parts like this in inventory as a standard logic building block.
