SN74LV244ATDBRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244AT is an octal buffer and line driver manufactured by Texas Instruments, designed for high-performance memory address drivers, clock drivers, and bus-oriented receivers. It operates within a supply voltage range of 4.5 V to 5.5 V and supports mixed-mode voltage operation on all ports. The device features TTL-voltage compatible inputs and provides three-state outputs controlled by separate output-enable (OE) inputs. It includes Ioff circuitry to support partial-power-down mode, preventing damaging backflow currents when powered down.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (DB, DGV, DW, NS, PW, or RGY) required for your design, as the base part number covers multiple physical form factors. Confirm that the 4.5 V to 5.5 V operating voltage aligns with your system's power rails. Ensure ESD protection requirements are met, as the device exceeds JESD 22 standards for machine and charged-device models.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with independent control over two groups of four bits. It is suitable for applications needing high-density solutions for bus-oriented data transmission. Verify that the 5.4 ns typical propagation delay meets your timing constraints at 5 V operation. Consider the available package options based on board space and thermal management needs.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LV series of low-voltage CMOS logic components from Texas Instruments. While many LV devices operate at lower voltages, the 'AT' suffix specifically denotes the 4.5 V to 5.5 V operational range. It serves as a robust interface solution for digital systems requiring signal buffering and direction control in standard 5 V logic environments.
