SN74ACT244DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT244DW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the advanced CMOS (ACT) logic family. It features eight non-inverting channels organized into two four-bit sections, each controlled by a separate output enable (OE) input. The device operates within a supply voltage range of 4.5V to 5.5V and provides three-state outputs with a maximum propagation delay of 9ns at 5V. It supports TTL-compatible inputs while delivering CMOS-level outputs, ensuring high-speed performance for bus-oriented applications.
