74ABT2244DB,112

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74ABT2244DB,112 is an octal buffer and line driver featuring 30Ω series termination resistors within each output path. It operates on a single 4.5V to 5.5V supply and provides two independent output enables (1OE, 2OE) controlling four outputs each. The device utilizes BiCMOS technology for high-speed performance with low power dissipation. Key electrical parameters include propagation delays of 2.8ns typical at 5V, input capacitance of 4pF, and output drive capabilities of +5mA/–32mA. It supports live insertion/extraction and ensures inputs are disabled during the 3-State mode.
