74LVC126ADB,118

Overview

The Nexperia 74LVC126ADB,118 is a quad buffer and line driver belonging to the LVC logic family. It features four non-inverting channels with three-state outputs controlled by an active-low output enable input. The device operates within a supply voltage range of 1.2 V to 3.6 V and supports high drive currents of 24 mA at both high and low states. Packaged in a TSSOP-14 surface-mount housing, it ensures signal integrity through Schmitt-trigger inputs and provides ESD protection exceeding 2000 V HBM.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state output control
• Features Schmitt-trigger action on all inputs for improved noise immunity and tolerance to slow rise/fall times
• Includes I_OFF circuitry to prevent damaging backflow current during partial power-down conditions
• Offers robust electrostatic discharge protection compliant with ANSI/ESDA/JEDEC standards

Applications

• Bus-oriented communications systems requiring signal buffering
• Clock distribution networks for timing signals
• Memory and storage applications utilizing data bus drivers
• Control logic interfacing between different voltage domains

Procurement Notes

Verify the specific suffix 'ADB' against official Nexperia documentation to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with your PCB footprint requirements for the TSSOP-14 configuration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when designing low-voltage digital circuits requiring buffered outputs with high drive capability. The wide supply range accommodates various logic families, while the three-state feature enables efficient bus sharing. Verify that the operating temperature range meets environmental specifications and that the package size fits the available board space constraints.

Part Context

This device is part of the extensive 74LVC logic portfolio from Nexperia, designed for low-voltage CMOS applications. It shares functional similarities with other buffers in the series but is distinguished by its specific pinout and packaging options. The LVC family is widely used in portable electronics and industrial controls due to its balance of speed, power consumption, and drive strength.

Replacement Considerations

Compatible substitutes include the 74LVC126APW and 74LVC126AD,118. Verify pin compatibility and electrical parameters before substitution.
