SN74LV244ATDWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ATDWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74LV logic family. It features non-inverting outputs with three-state control, organized into two independent four-bit sections. The device operates within a supply voltage range of 2V to 5.5V and supports mixed-mode operation allowing different input and output voltages. It is housed in a 20-pin TSSOP package and is designed for high-density memory address and clock driving applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffers or drivers with three-state outputs controlled by separate enable inputs.
