74HC1G125GV-Q100H

Overview

The Nexperia 74HC1G125GV-Q100H is a single non-inverting buffer and line driver featuring a three-state output, housed in an SC-74A (SOT753) plastic surface-mounted package with five leads. 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 complies with AEC-Q100 Grade 1 standards for automotive applications. Static characteristics specify input leakage current up to 1.0 μA at 6.0 V and off-state output current up to 10 μA. Dynamic performance includes propagation delays ranging from 8 ns to 150 ns depending on voltage and temperature.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Wide operating supply voltage range from 2.0 V to 6.0 V
• High noise immunity with symmetrical output impedance
• ESD protection exceeding 2000 V via Human Body Model

Applications

• Automotive electronic systems requiring robust signal buffering
• Driving high-capacitance or transmission-line loads
• Bus-oriented architectures utilizing three-state control

Procurement Notes

Verify the specific suffix 'H' against official Nexperia documentation to confirm if it denotes a specific tape-and-reel configuration or marking variation distinct from the standard '125' suffix. Ensure the SC-74A package variant matches the required footprint constraints. Confirm that the AEC-Q100 Grade 1 qualification meets the thermal and reliability requirements of the target automotive environment before finalizing procurement.

Selection Notes

Select this component when a single-channel buffer with three-state capability is required for automotive-grade designs. The HC logic family provides CMOS input levels suitable for interfacing with other CMOS devices across a wide voltage spectrum. Consider the SC-74A package dimensions for space-constrained PCB layouts. Verify that the input clamp diodes are sufficient for the intended interface voltages without external current-limiting resistors.

Part Context

This device belongs to the Nexperia 74HC_HCT1G125-Q100 series of bus buffers and line drivers. It shares functional similarities with the 74HCT1G125GV-Q100H but utilizes HC logic thresholds rather than TTL-compatible inputs. The GV suffix indicates the SC-74A package type, while the Q100 designation confirms automotive qualification. This series is designed for high-speed signal integrity in demanding environments.

Replacement Considerations

The 74HC1G125GW-Q100 serves as a direct functional substitute using the TSSOP5 package instead of SC-74A. For TTL-level input requirements, the 74HCT1G125GV-Q100H offers identical functionality with compatible pinouts. Verify package compatibility and input threshold specifications when substituting.
