SN74AUP1G125DSFR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUP1G125DSFR is a low-power single bus buffer gate with 3-state output from the Texas Instruments AUP family. It operates within a supply voltage range of 0.8 V to 3.6 V and supports an operating temperature range of -40°C to +85°C. The device features a maximum propagation delay of 4.6 ns at 3.3 V, low static power consumption (ICC = 0.9 µA maximum), and low dynamic power consumption (Cpd = 4 pF typical). It includes input-disable functionality for floating conditions and Ioff support for partial-power-down mode operation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features balanced high-drive CMOS push-pull outputs capable of sinking and sourcing similar currents for fast signal edges.
• Supports partial-power-down mode operation via Ioff circuitry that disables outputs when the supply voltage is removed.
• Incorporates over-voltage tolerant inputs allowing signals to be driven above the supply voltage without damage.

• Blu-ray players and home theaters
• Solid-state drives (SSD) for client and enterprise use
• LCD/Digital and High-Definition (HDTV) televisions
• Wireless headsets, keyboards, and mice

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and tape-and-reel configuration against the manufacturer's current orderable addendum. Confirm that the DSF SON package variant matches the required footprint dimensions and pinout orientation for the target PCB layout. Ensure compliance with RoHS directives and check for any recent manufacturing site changes documented in product change notifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low static and dynamic power consumption across a wide voltage range. It is suitable for mixed-mode signal operations due to its 3.6-V I/O tolerance. Consider the input-disable feature if floating input conditions are possible during system operation. Evaluate thermal performance based on the specific PCB layout and ambient temperature constraints.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial-power-down scenarios?

The SN74AUP1G125 supports partial-power-down mode through its Ioff circuitry. When the supply voltage drops to 0 V, the inputs and outputs enter a high-impedance state, inhibiting current backflow into the device to prevent damage.

Can the inputs tolerate voltages higher than the supply voltage?

Yes, the device features over-voltage tolerant inputs. Input signals can be driven above the supply voltage, provided they remain below the maximum input voltage value specified in the Absolute Maximum Ratings table.
