74AHCT1G02GW-Q100H

Overview

The Nexperia 74AHCT1G02GW-Q100H is a single 2-input NOR gate qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-level inputs. The device utilizes a TSSOP5 (SOT353-1) package with five leads. Static characteristics include an input leakage current maximum of 2.0 μA at -40 °C to +125 °C. Dynamic performance specifies a propagation delay of up to 9.5 ns at 5.5 V with 50 pF load capacitance.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 specifications
• Overvoltage tolerant inputs allowing operation up to 5.5 V regardless of supply voltage
• TTL-compatible input levels ensuring compatibility with standard logic families
• High noise immunity and balanced propagation delays

Applications

• Automotive electronic systems requiring robust logic gating
• Mixed voltage environments utilizing overvoltage tolerant interfaces
• Signal processing circuits requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the GW designation corresponds to the TSSOP5 plastic thin shrink small outline package. Confirm that the AHCT series selection aligns with system requirements for TTL-level input thresholds rather than CMOS levels found in the AHC variant. Ensure environmental compliance checks are performed against project-specific REACH or RoHS constraints before finalizing procurement orders.

Selection Notes

Select this component when TTL-level input compatibility is mandatory within a 5 V logic environment. The AEC-Q100 Grade 1 qualification makes it suitable for automotive use cases where extended temperature ranges from -40 °C to +125 °C are required. Consider the TSSOP5 package dimensions if board space is constrained, noting the body width specification. Verify that the 5.5 V maximum input tolerance meets interface requirements for any upstream components operating at higher voltages.

Part Context

This part belongs to the 74AHC_AHCT1G02-Q100 family of single 2-input NOR gates manufactured by Nexperia. The datasheet covers both AHC and AHCT variants, distinguished primarily by their input voltage level requirements. The product line is designed for general-purpose logic applications with specific emphasis on automotive reliability and mixed-voltage translation capabilities.

Replacement Considerations

The 74AHC1G02GW-Q100H serves as a functional substitute if CMOS-level inputs are acceptable instead of TTL levels. Other packages such as SC-74A (GV) or XSON5 (GZ) offer alternative form factors but require footprint verification.
