SN74AUC2G00DCTR

Overview

The SN74AUC2G00DCTR is a dual 2-input positive-NAND gate from the Texas Instruments AUC logic series, housed in an 8-pin SSOP (DCT) package. It operates within a supply voltage range of 0.8 V to 2.7 V, optimized for 1.65 V to 1.95 V applications. The device delivers ±8-mA output drive at 1.8 V and achieves a maximum propagation delay of 1.2 ns at 1.8 V with a 15 pF load. It supports partial-power-down mode via Ioff circuitry and features ESD protection exceeding 2000 V (Human-Body Model).

Feature Summary

• Implements the Boolean NAND function Y = A·B or Y = A+B using CMOS technology.
• Incorporates Ioff circuitry to disable outputs during power-down, preventing damaging backflow current.
• Provides high latch-up performance exceeding 100 mA per JESD 78 Class II standards.
• Features robust ESD protection ratings across Human-Body, Machine, and Charged-Device Models.

Applications

• Mixed-mode signal processing supporting 3.6-V I/O tolerance.
• Partial-power-down applications requiring controlled output disabling.
• Low-voltage digital logic circuits operating between 0.8 V and 2.7 V.

Procurement Notes

Verify the specific ordering suffix 'DCTR' corresponds to the SSOP (DCT) package type and reel quantity of 3000 units. Confirm that the component meets RoHS compliance and Level-1 moisture sensitivity rating requirements for your assembly process. Ensure the operating temperature range of -40°C to +85°C aligns with your system specifications before finalizing procurement.

Selection Notes

Select this component when designing low-power digital systems requiring fast switching speeds under 2.7 V supplies. The SSOP package offers a compact footprint suitable for space-constrained PCB layouts. Consider the ±8-mA drive capability for moderate fan-out requirements without external buffering. Verify input voltage thresholds against your logic levels to ensure reliable switching at the target supply voltage.

Part Context

This device belongs to the SN74AUC2Gxx family of ultra-low-voltage CMOS logic gates. The AUC series is engineered for sub-1-V operation while maintaining high-speed performance comparable to higher voltage counterparts. The dual-gate configuration allows multiple logic functions to be integrated into a single small outline package, reducing board space and component count in portable and battery-operated electronics.
