74LVC1G126DCKRG4

Overview

The SN74LVC1G126DCKRG4 is a single bus buffer gate with three-state outputs manufactured by Texas Instruments. It belongs to the LVC logic series and operates within a supply voltage range of 1.65 V to 5.5 V. The device features non-inverting polarity and provides high-level output current of -32 mA and low-level output current of 32 mA. It has a maximum static current of 10 µA and functions reliably across an operating temperature range from -40 °C to +125 °C. The component is housed in a SC-70-5 surface-mount package.

Feature Summary

• Provides single-channel buffering with three-state output capability for effective bus isolation
• Supports wide supply voltage operation ranging from 1.65 V to 5.5 V
• Features robust drive strength with 32 mA output current capability at both logic levels
• Designed for industrial temperature environments with extended thermal stability

Applications

• Bus-oriented memory and address drivers
• Clock distribution and buffering
• Voltage translation between different logic domains
• High-speed data line termination and driving

Procurement Notes

Verify the specific ordering suffix 'R4' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the SC-70-5 package dimensions align with the target PCB footprint constraints. Ensure compliance with RoHS directives and check for any recent product change notices regarding manufacturing site or material composition updates before finalizing procurement orders.

Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is required for bus applications. It is suitable for designs needing wide voltage compatibility and high drive current in a minimal footprint. Consider the SC-70-5 package size for space-constrained layouts. Evaluate the 10 µA static current consumption against power budget requirements for battery-operated systems.

Part Context

This part is a member of the Texas Instruments 74LVC family, which utilizes advanced CMOS technology to achieve high-speed operation while maintaining low power consumption. The LVC series is designed to be pin-compatible with legacy 74HC devices but offers improved performance characteristics including wider voltage ranges and faster switching speeds, making it ideal for modern embedded systems requiring efficient signal management.

Replacement Considerations

The SN74LVC1G126DBVTG4 serves as a verified alternative offering identical logical functionality in a SOT-23-5 package. Designers must verify mechanical fit and soldering profile compatibility when substituting between the SC-70-5 and SOT-23-5 form factors.
