SN74LV244APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244APWR is an octal buffer and line driver from Texas Instruments, belonging to the LV logic series. It features eight non-inverting channels with three-state outputs housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2 V to 5.5 V and supports a maximum propagation delay of 6.5 ns at 5 V. It provides high drive capability with output currents of 16 mA for both high and low states. The component functions as two independent four-bit drivers, each with separate output enable inputs, designed for memory address driving and bus-oriented applications.

• Memory address drivers for storage systems
• Clock signal distribution networks
• Bus-oriented receiver and transmitter circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific revision level and RoHS compliance status directly against the manufacturer's latest documentation before integration. Confirm that the TSSOP-20 footprint matches the target PCB design constraints. Ensure the operating environment remains within the specified temperature range of -40°C to +85°C for reliable performance. Cross-reference the ordering suffix to guarantee the correct packaging format required for assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 2 V and 5.5 V rails. It is suitable for applications needing high-density octal buffering with controlled signal integrity. Consider the 6.5 ns maximum delay for timing-critical paths. The three-state output capability allows efficient bus sharing without additional gating logic. Verify thermal requirements for the TSSOP package under continuous load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A family of CMOS logic devices manufactured by Texas Instruments. It is specifically engineered to improve density and performance in three-state memory address drivers and clock drivers. The LV series offers broader voltage flexibility compared to traditional 5 V-only logic families, making it adaptable for modern mixed-voltage digital interfaces.
