SN74LVC244AZQNR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244AZQNR is an automotive-grade octal buffer and line driver from Texas Instruments, belonging to the LVC logic family. It features eight non-inverting channels with three-state outputs, designed for low-voltage operation between 1.65V and 3.6V. The device supports mixed-mode signal operations, allowing 5V tolerant inputs while operating on lower supply voltages. It utilizes a Microstar Junior BGA-20 package suitable for space-constrained applications. Key electrical characteristics include a propagation delay of approximately 6.5ns at 3.3V, output drive currents of ±24mA, and a wide operating temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific suffix 'ZQNR' confirms automotive grade qualification and the Microstar Junior package type. Ensure the procurement source provides valid traceability documentation required for automotive assembly processes. Confirm RoHS compliance status matches current manufacturing specifications before finalizing orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for automotive environments requiring robust signal integrity and mixed-voltage compatibility. The LVC series offers superior speed-to-power efficiency compared to standard CMOS alternatives. Consider the BGA-20 footprint constraints and thermal dissipation requirements inherent to the Microstar Junior package layout during PCB design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC244A family of octal buffers. Unlike the standard commercial SN74LVC244ADW, the ZQNR suffix denotes automotive qualification. It shares functional similarities with other LVC devices but is distinct from the bidirectional SN74LVC245 variants. The device serves as a critical interface element for translating and strengthening digital signals within complex automotive electronic architectures.
