SN74AUC16240DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC16240DGGR is a 16-bit buffer/driver from the Widebus family, housed in a 48-pin TSSOP package. It operates at supply voltages (VCC) ranging from 0.8 V to 2.7 V, with specific optimization for 1.65 V to 1.95 V applications. The device provides symmetrical active-low output-enable inputs and delivers sub-1-V operability. Key electrical parameters include a maximum propagation delay of 2 ns at 1.8 V, ±8 mA output drive capability at 1.8 V, and a maximum quiescent current of 20 µA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports partial-power-down mode operation via Ioff circuitry that disables outputs to prevent damaging backflow currents during power-down states.
• Designed specifically for mixed-mode signal environments by providing 3.6-V I/O tolerance while operating at lower 1.8-V logic levels.
• Configurable as four 4-bit buffers, two 8-bit buffers, or one single 16-bit buffer to accommodate various bus-oriented architectures.

• Memory address drivers requiring high density and improved performance
• Clock distribution networks within low-voltage systems
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the orderable part number SN74AUC16240DGGR against the latest Texas Instruments Package Option Addendum to confirm status and material type. Ensure compatibility with the specified -40°C to 85°C operating temperature range and Level-1 moisture sensitivity rating prior to integration into manufacturing workflows.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring 16-bit buffering with inverted outputs and active-low enable control. It is suitable for applications demanding sub-1-V operation and 3.6-V I/O tolerance. Verify that the system voltage falls within the 0.8 V to 2.7 V range and that the required output drive strength aligns with the ±8 mA specification at 1.8 V.
