SN74LS244DWR TI Buffers, Drivers, Receivers, Transceivers
The SN74LS244 is an octal buffer and line driver with 3-state outputs, featuring two independent 4-bit buffers, each with an active-low output enable. It operates from a 4.75-V to 5.25-V supply with TTL-compatible inputs, providing a high output drive of ±15 mA and a typical propagation delay of 12 ns. Packaged in a 20-pin SOIC (DW) (12.8 mm × 7.5 mm), it is standard for 5-V bus-oriented systems requiring high drive and low propagation delay. Applications include memory address drivers, backplane bus interfacing, data bus buffering in microprocessor-based systems, and peripheral driving in industrial controls.
