74AHCT1G02GZYL

Overview

The 74AHCT1G02GZYL is a single 2-input NOR gate from the Nexperia 74AHCT series, housed in a 5-XSON (1.1x0.85 mm) surface-mount package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. The device features TTL input levels, high noise immunity, and low power dissipation. It includes overvoltage tolerant inputs up to 5.5 V, making it suitable for mixed-voltage environments. Static current is typically 1 µA maximum, with output drive capabilities of 8 mA high and 8 mA low.

Feature Summary

• Single 2-input NOR logic function
• TTL-compatible input switching levels
• Overvoltage tolerant inputs up to 5.5 V
• Wide supply voltage operation from 2.0 V to 5.5 V

Applications

• Mixed voltage level translation between 3.3 V and 5 V systems
• General purpose digital logic processing
• Signal gating in embedded control circuits

Procurement Notes

Verify the specific suffix GZYL corresponds to the 5-XSON package and reel quantity requirements when ordering. Confirm that the AHCT variant matches your system's TTL input threshold needs rather than CMOS thresholds. Ensure design compatibility with the specified 2.0 V to 5.5 V supply range and industrial temperature limits before finalizing procurement specifications.

Selection Notes

Select this component when a compact NOR gate is required for space-constrained designs using the small 5-XSON footprint. Choose the AHCT series specifically if the upstream logic outputs TTL levels, as opposed to the AHC series which requires CMOS levels. Verify that the 5.5 V overvoltage tolerance on inputs aligns with the highest voltage present in the signal chain to prevent damage during interface operations.

Part Context

This part belongs to Nexperia's 74AHCT family of high-speed Si-gate CMOS devices. These components are pin-compatible with Low-power Schottky TTL (LSTTL) standards. The 74AHCT1G02GZYL represents a miniaturized version of the traditional quad NOR gate, offering a single gate solution in an ultra-small outline no-lead package for modern PCB density requirements.

Replacement Considerations

Direct functional equivalents include other single 2-input NOR gates in similar packages such as the 74AHCT1G02GV or 74HCT1G02 variants. Cross-reference package dimensions and electrical characteristics like propagation delay and output current against the original design requirements to ensure seamless integration without circuit modification.
