SN74AUC1G08DBVR

Overview

The SN74AUC1G08DBVR is a single 2-input positive-AND 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 an output drive current of ±8 mA at 1.8 V. The device incorporates Ioff circuitry to prevent backflow during partial-power-down states and offers ESD protection exceeding 2000 V via the human-body model. It is housed in a 5-pin SOT-23 package.

Feature Summary

• Operates at sub-1-V supply voltages with optimized performance for 1.8-V logic levels
• Includes Ioff circuitry to support partial-power-down mode and back-drive protection
• Provides high electrostatic discharge protection exceeding JESD 22 standards

Applications

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

Procurement Notes

Verify that the specific orderable part number matches the required package type and tape-and-reel quantity. Confirm compliance with RoHS directives and lead finish specifications before procurement. Ensure the component status is listed as active production to guarantee long-term availability and consistency with the datasheet parameters.

Selection Notes

Select this component when designing mixed-mode signal circuits requiring 3.6-V I/O tolerance while operating at lower core voltages. The device is suitable for applications demanding low power consumption with a maximum ICC of 10 µA. Consider the SOT-23 package dimensions for space-constrained portable electronics designs.

Part Context
