SN74LVC2244ADBQR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2244ADBQR is an octal buffer and line driver manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features non-inverting logic with three-state outputs. The device utilizes LVC logic technology and is housed in a TSSOP-20 package. It supports input voltages up to 5.5 V, enabling direct interfacing between 5-V devices and 3.3-V systems.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffers with three-state outputs for signal isolation and driving
• Supports 5-V tolerant inputs allowing direct connection to 5-V devices while operating at lower voltages
• Designed for low-voltage applications with operation down to 1.65 V

• Memory card controllers
• Clock buffering and distribution
• High-speed data bus drivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification requirements. Confirm the 'R' suffix corresponds to tape-and-reel packaging specifications. Ensure the TSSOP-20 package dimensions match the design footprint. Cross-reference the RoHS status with current environmental compliance standards before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 5-V tolerance on inputs alongside low-voltage operation. The LVC series offers improved switching speeds compared to standard LV counterparts. Verify that the thermal performance of the TSSOP-20 package meets the application's power dissipation limits under maximum load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC2244A family of octal buffers. It serves as a high-performance solution for managing complex digital interfaces where signal integrity and voltage translation are critical. The device complements other logic families by providing robust drive capabilities in compact packages suitable for space-constrained designs.
