SN74AUP3G17DCUR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUP3G17DCUR is a triple Schmitt-trigger buffer manufactured by Texas Instruments, belonging to the AUP logic series. It features three non-inverting input lines and three corresponding output lines housed in an 8-pin VSSOP package. The device operates within a supply voltage range of 0.8 V to 3.6 V. Key electrical specifications include a maximum propagation delay of 4.3 ns, with output drive capabilities of -4 mA for high level and 4 mA for low level. Static current consumption is specified at 500 nA, while operating power current reaches 900 nA. The component supports surface-mount installation and functions reliably across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DCUR corresponds to the VSSOP-8 package and reel packaging configuration required for your assembly process. Confirm that the AUP series voltage limits (0.8V to 3.6V) align with your system's power rails, as exceeding these values may damage the component. Ensure thermal management meets the -40°C to +85°C operational requirements for your intended environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when three-channel Schmitt-trigger functionality is required in a compact VSSOP footprint. The AUP series offers lower power consumption compared to standard LVC or LVCMOS alternatives, making it ideal for energy-constrained designs. Verify that the 4 mA output drive strength is sufficient for your load capacitance and trace requirements without necessitating additional buffering stages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUPxGxx family of single-gate logic ICs from Texas Instruments. These components are designed for ultra-low-power applications requiring small form factors. The SN74AUP3G17 specifically provides triple buffering with Schmitt-trigger inputs, distinguishing it from standard buffers like the SN74AUP3G04 which lacks hysteresis. It complements other AUP series devices such as the SN74AUP2G17 for dual-channel needs.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the primary function of the Schmitt-trigger inputs in this buffer?

The Schmitt-trigger inputs provide hysteresis, which filters out noise and ensures clean, fast transitions between logic states even when the input signal has slow rise or fall times.

How does the AUP series differ from the LVC series regarding voltage?

The AUP series operates at a lower voltage range (0.8 V to 3.6 V) compared to the LVC series (1.65 V to 5.5 V), offering lower power consumption but requiring compatible low-voltage power supplies.
