74HCT1G125GV-Q100H

Overview

The Nexperia 74HCT1G125GV-Q100H is a single non-inverting buffer and line driver featuring a three-state output, housed in a SC-74A (SOT753) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device accepts TTL input levels and provides high noise immunity with balanced propagation delays. It includes clamp diodes on the inputs for interfacing voltages exceeding VCC. The component meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Wide operating temperature range specified from -40 °C to +125 °C
• TTL input switching levels compatible with standard logic families
• High noise immunity and symmetrical output impedance

Applications

• Automotive electronic systems requiring qualified logic buffers
• Bus-oriented transmissions utilizing three-state outputs
• Line driving applications needing high noise immunity

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature grade. Confirm compliance with RoHS directives and REACH regulations prior to integration. Ensure design safeguards account for the absolute maximum ratings to prevent permanent damage. Validate that the application environment remains within the specified thermal and electrical limits defined in the datasheet.

Selection Notes

Select this component when a single-channel buffer with three-state control is required for automotive environments. The HCT series ensures compatibility with TTL logic thresholds, distinguishing it from HC variants. Verify that the SC-74A package dimensions fit the PCB layout constraints. Consider the power dissipation derating characteristics if operating near the upper temperature limit.

Part Context
