SN74AUC1G32DBVRG4

Overview

The SN74AUC1G32DBVRG4 is a single 2-input positive-OR gate from the Texas Instruments AUC series, designed for operation within a supply voltage range of 0.8 V to 2.7 V. It features a maximum propagation delay of 2.4 ns at 1.8 V and supports ±8-mA output drive current. The device includes Ioff partial-power-down mode to prevent backflow currents when powered down. It provides ESD protection exceeding 2000 V via the human-body model and 1000 V via the charged-device model. The component is housed in a five-pin SOT-23 package.

Feature Summary

• Operates at sub-1-V supply voltages with optimized performance for 1.8-V systems.
• Features Ioff circuitry that disables outputs to prevent damaging backflow during partial-power-down states.
• Provides high electrostatic discharge protection exceeding standard industry thresholds.

Applications

• Portable audio devices such as MP3 players and recorders
• Solid-state drives for client and enterprise storage
• Wireless peripherals including headsets, keyboards, and mice

Procurement Notes

Verify the specific ordering suffix 'G4' confirms RoHS compliance and lead-free status as defined in the manufacturer's packaging addendum. Confirm the package type matches the required PCB footprint, specifically the SOT-23 configuration for this variant. Ensure design specifications align with the recommended operating conditions regarding supply voltage and temperature ranges before finalizing procurement.

Selection Notes

Select this component for designs requiring low-voltage logic operations between 0.8 V and 2.7 V. It is suitable for mixed-mode signal environments due to its 3.6-V I/O tolerance. Consider the Ioff feature if the system requires safe disconnection during power-down states. Evaluate the propagation delay characteristics against the target clock speeds to ensure timing requirements are met.

Part Context
