SN74LVC244ADGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244ADGVR is an octal buffer and line driver from the Texas Instruments LVC logic family, housed in a 20-pin TVSOP package. It operates within a supply voltage range of 1.65 V to 3.6 V. The device features non-inverting polarity with three-state outputs and eight input lines. Key electrical parameters include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delay is specified at 6.7 ns at 2.7 V and 5.7 ns at 3.3 V. It supports a wide operating temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-20 package and tape-and-reel orientation required for your assembly process. Confirm RoHS compliance status and ensure the component meets the thermal requirements for your intended operating environment. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and availability before finalizing procurement orders.

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 low static power consumption and fast switching speeds within the 1.65 V to 3.6 V supply range. Consider the TVSOP-20 package constraints regarding board space and thermal dissipation capabilities compared to other available packages in the same logic family.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC244A series, which is part of Texas Instruments' broader LVC (Low-Voltage CMOS) logic portfolio. The LVC series is designed for low-power applications requiring high speed. The SN74LVC244A specifically provides octal buffering with three-state outputs, making it a standard solution for managing data flow on system buses in consumer electronics and industrial equipment.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVC244ADWR as a potential alternative if a wider SOIC package is acceptable instead of the TVSOP form factor. Verify pin compatibility and electrical specifications against the original design requirements before substituting.
