SN74AUCH16244DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUCH16244DGVR is a 16-bit buffer and driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 2.7 V, optimized for 1.65 V to 1.95 V operation. The device features symmetrical active-low output-enable inputs and provides true outputs. It supports mixed-mode signal operation with 3.6-V I/O tolerance. Key electrical parameters include a maximum propagation delay of 1.8 ns at 1.8 V and an output drive capability of ±8 mA at 1.8 V. The package type is TVSOP-48.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Optimized for 1.8-V operation with 3.6-V I/O tolerance to support mixed-mode signal environments
• Features bus hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors
• Supports partial-power-down mode via Ioff circuitry that disables outputs to prevent damaging backflow current
• Includes latch-up performance exceeding 100 mA per JESD 78, Class II specifications

Buffers, Drivers, Receivers, Transceivers Applications

• 3-state memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-48 tape and reel packaging configuration. Confirm RoHS compliance status and lead finish details (NIPDAU) against the latest manufacturer documentation. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density 16-bit buffering with low power consumption. It is suitable for applications needing sub-1-V operability and fast switching speeds. Consider the TVSOP-48 package constraints for PCB layout. Verify input transition rates do not exceed recommended limits to ensure proper functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Widebus family of logic ICs from Texas Instruments. It is designed to improve performance and density in digital circuits. The SN74AUCH16244 serves as a non-inverting buffer/driver. It can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer depending on system requirements.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74AUCH16244DGGR if TSSOP-48 packaging is required instead of TVSOP-48. Verify pinout compatibility before substitution. Review datasheet revisions for any changes in electrical characteristics or thermal impedance values.
