SN74LVC2244ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2244ADW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the LVC logic family. It features two independent four-bit buffers with three-state outputs housed in a 20-TSSOP package. The device operates within a supply voltage range of 1.65V to 3.6V and supports mixed-mode operation across all ports. Key electrical parameters include high-level output current of -12mA and low-level output current of 12mA. Static current is specified at 10µA, with a maximum operating temperature of 85°C.
