74HC2G125DC-Q100H

Overview

The Nexperia 74HC2G125DC-Q100H is a dual buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes CMOS technology for low power dissipation and high noise immunity. It includes input clamp diodes, allowing interface to voltages exceeding VCC using current-limiting resistors. The component is packaged in an 8-lead VSSOP plastic package (SOT765-1) and meets AEC-Q100 Grade 1 qualification standards.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Wide operating temperature range extending up to +125 °C
• High noise immunity with latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Robust electrostatic discharge protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Automotive electronic systems requiring qualified logic components
• Bus-oriented transmissions utilizing 3-state buffering
• Clock distribution and buffering circuits
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the procurement documentation aligns with the latest product data sheet revision. Ensure compliance with automotive quality requirements if intended for such applications. Check for any specific environmental compliance declarations relevant to the destination market.

Selection Notes

Select this component when a dual buffer with 3-state control is required for automotive or industrial environments. The HC series offers CMOS input levels suitable for standard logic interfacing. Consider the VSSOP package dimensions for space-constrained PCB layouts. Verify that the supply voltage and load capacitance requirements fall within the specified dynamic characteristics limits.

Part Context

This part belongs to the Nexperia 74HC_HCT2G125-Q100 family of dual buffers and line drivers. It shares functional similarities with other members like the 74HCT2G125DC-Q100H but differs in input voltage thresholds. The family is designed for high-performance CMOS applications with wide supply voltage ranges and robust ESD protection capabilities across various small outline packages.

Replacement Considerations

The 74HCT2G125DC-Q100H serves as a compatible alternative within the same family, offering TTL-compatible input levels instead of CMOS levels. Designers must verify input voltage threshold compatibility when substituting between HC and HCT variants.
