SN74LV244ADB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ADB is an octal buffer and line driver manufactured by Texas Instruments, utilizing CMOS technology. It operates within a supply voltage range of 2V to 5.5V and features three-state outputs controlled by two independent output-enable inputs. The device is organized into two separate four-bit drivers, each with its own control logic. Designed for high-density applications, it supports mixed-mode voltage operation across all ports and includes partial power-down mode functionality via the Ioff feature. The component provides enhanced signal integrity with optimized output characteristics and robust ESD protection exceeding JESD 22 standards.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode voltage operation allowing simultaneous use of different voltage levels on input and output ports
• Features partial power-down mode capability through Ioff circuitry to minimize current consumption during standby
• Provides enhanced signal integrity with optimized output voltage overshoot and undershoot performance

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers in computer systems
• Clock drivers for timing distribution networks
• Bus-oriented receivers and transmitters in communication interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the SN74LV244ADB designation typically corresponds to the SOIC-20 package. Confirm RoHS compliance status and check for alternative suffixes such as ADWE or ADBR which may indicate different packaging or environmental certifications. Ensure the selected part matches the required operating temperature range and pinout configuration for the target PCB layout.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 2V and 5.5V. It is suitable for applications needing high-speed buffering with low propagation delay. Consider the SN74LV244ADW for tube packaging or SN74LV244ADWR for tape-and-reel options if different handling requirements exist. Evaluate the need for three-state isolation and mixed-voltage interface capabilities before finalizing the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments SN74LV series of low-voltage CMOS logic components. The LV family is engineered to provide high-speed performance while maintaining compatibility with standard 5V and lower voltage logic families. The octal buffer configuration allows for efficient management of multiple signal lines within a single integrated circuit package.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LV244ADW serves as a functional equivalent with identical electrical specifications but utilizes tube packaging instead of tape-and-reel. SN74LV244ADWR offers the same core functionality with reel packaging for automated assembly processes.
