74HC1G126GV,125

Overview

The Nexperia 74HC1G126GV,125 is a single bus buffer and line driver featuring a three-state output. It operates within a supply voltage range of 2.0 V to 6.0 V and utilizes the SC-74A (SOT753) surface-mount package with five leads. The device provides CMOS low power dissipation, symmetrical output impedance, and high noise immunity. It complies with JEDEC standards JESD8C and JESD7A, ensuring compatibility across various logic families.

Feature Summary

• Single-channel non-inverting buffer with three-state output capability controlled by an enable input
• Wide operating supply voltage range from 2.0 V to 6.0 V for flexible system integration
• High noise immunity and balanced propagation delays for reliable signal transmission
• Robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Bus-oriented transmissions in digital systems
• Clock drivers requiring high fan-out capabilities
• Memory and address bus buffering applications
• Line drivers for signal integrity maintenance

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature rating. Confirm that the SC-74A package variant matches the intended PCB footprint requirements. Cross-reference the datasheet revision date to ensure compliance with the latest JEDEC ESD protection specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-channel buffer with three-state control is required for voltages up to 6.0 V. The HC series offers standard CMOS input levels suitable for general-purpose logic interfacing. Consider the SC-74A package dimensions for space-constrained designs. Ensure the application environment remains within the specified -40 °C to +125 °C operating temperature range.

Part Context

This device belongs to the Nexperia 74HC1G1xx family of single-gate logic ICs. These components are designed for low-power, high-speed CMOS applications. The 74HC1G126 specifically functions as a buffered line driver, providing isolation and drive strength for data lines while maintaining signal fidelity across mixed-voltage environments.

Replacement Considerations

The 74HCT1G126GV,125 serves as a functional replacement within the same package, offering TTL-compatible input levels instead of CMOS levels. Verify that the target circuit inputs can tolerate the different switching thresholds associated with the HCT series before substituting.
