74AUP1G373GM,132

Overview

The Nexperia 74AUP1G373GM,132 is a single D-type transparent latch with 3-state outputs. It operates within a supply voltage range of 0.8 V to 3.6 V and features Schmitt-trigger inputs for noise immunity. The device includes IOFF circuitry for partial power-down applications. It is housed in an XSON6 (SOT886) package measuring 1 x 1.45 x 0.5 mm. Propagation delay from data input to output ranges from 1.5 ns to 6.4 ns depending on load capacitance and voltage.

Feature Summary

• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.
• IOFF circuitry disables the output during power-down to prevent damaging backflow current.
• CMOS low power dissipation ensures very low static and dynamic power consumption across the entire supply voltage range.

Applications

• Partial power-down mode operation
• Data storage and buffering in low-voltage systems
• Signal latching with high noise immunity requirements

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the XSON6 form factor aligns with PCB layout constraints. Ensure compatibility with the target system's voltage levels and signal integrity requirements before finalizing procurement.

Selection Notes

Select this component when a single-channel latch with three-state control is needed in a compact footprint. The wide operating voltage range supports various logic families. Consider the propagation delay specifications relative to the system clock speed and load conditions to ensure timing compliance.

Part Context

This part belongs to the 74AUP series of low-power CMOS logic devices. The AUP family is designed for applications requiring low power consumption and high-speed performance. The 74AUP1G373 specifically provides a single latch function within a minimal surface-mount package suitable for space-constrained designs.

Replacement Considerations

Check pinout compatibility and electrical characteristics against alternative single D-latch components. Verify that substitute parts support the same 3-state functionality and voltage range. Ensure the replacement package matches the existing board footprint or allows for re-layout.

FAQ

What is the function of the IOFF circuitry?

The IOFF circuitry disables the output when the device is powered down, preventing potentially damaging backflow current through the device.

How does the Schmitt-trigger feature benefit this latch?

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times, improving noise immunity.
