SN74AUC1G02DRLR

Overview

The SN74AUC1G02DRLR is a single 2-input positive-NOR gate from the AUC series, operating at supply voltages between 0.8 V and 2.7 V. It features low power consumption with a maximum ICC of 10 µA and supports partial-power-down mode via Ioff circuitry. The device provides ±8 mA output drive at 1.8 V and exhibits a maximum propagation delay of 2.4 ns at 1.8 V with a 30 pF load. It includes ESD protection exceeding 2000 V (HBM) and latch-up performance exceeding 100 mA per JESD 78 Class II. The component is housed in a DRL package.

Feature Summary

• Operates within a wide voltage range of 0.8 V to 2.7 V, optimized for 1.65 V to 1.95 V applications.
• Supports partial-power-down mode through integrated Ioff circuitry that disables outputs to prevent backflow current.
• Provides robust ESD protection exceeding 2000 V human-body model and 1000 V charged-device model ratings.
• Features high-speed switching capabilities with a maximum propagation delay of 2.4 ns at 1.8 V.

Applications

• Mixed-mode signal operation supporting 3.6-V I/O tolerance
• Partial-power-down applications requiring controlled output disabling
• Low-voltage digital logic circuits

Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the exact package type, lead finish, and moisture sensitivity level. Ensure the selected variant matches the required thermal impedance and reflow temperature profile for the intended assembly process. Confirm RoHS compliance status and check for any active production or preproduction designations before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring sub-1-V operability combined with fast switching speeds. The AUC series is suitable for applications needing low static power consumption alongside high noise immunity. Consider the DRL package dimensions and solder paste requirements during layout. Verify that the input transition rates remain within specified limits to ensure optimal propagation delay performance across the full operating temperature range.

FAQ

How does the Ioff feature benefit system design?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device. This allows multiple devices to share a common power rail without interference during partial-power-down states.

What is the maximum input voltage tolerance?

The input voltage range extends up to 3.6 V, allowing the device to tolerate 3.6-V signals even when operating at lower supply voltages such as 1.8 V. This facilitates mixed-mode signal operation.
