74LVC1G126DBVTG4

Overview

The SN74LVC1G126DBVTG4 is a single bus buffer gate with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an output current of ±32 mA. The device features low static current consumption of 10 µA and functions across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23 (SC-70) format, it provides unidirectional signal buffering with high-level control enable functionality.

Feature Summary

• Provides single-channel non-inverting buffering with three-state output capability for effective bus isolation
• Supports wide supply voltage operation ranging from 1.65 V to 5.5 V for flexible system integration
• Features robust drive strength with ±32 mA output current capability
• Designed for industrial applications with extended operating temperature coverage up to +125°C

Applications

• Bus buffering in embedded systems requiring signal isolation
• Interface circuits between different voltage domains
• High-speed data line drivers in portable devices
• Industrial control systems operating in extreme temperatures

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the ordering suffix matches the required tape-and-reel or cut-tape configuration for your assembly process. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing facility. Ensure the component meets the specified humidity sensitivity level requirements for your reflow soldering profile.

Selection Notes

Select this component when a single-channel buffer with three-state control is required for bus architectures. Consider the SOT-23 package size constraints and the need for ±32 mA drive strength. Evaluate the 1.65 V to 5.5 V supply range compatibility with your system power rails. Verify that the extended temperature range meets your operational environment specifications compared to commercial grade alternatives.

Part Context

This part belongs to the Texas Instruments 74LVC logic family, which offers CMOS performance with TTL-compatible inputs. The LVC series is designed for low-voltage applications while maintaining high speed and noise immunity. As a single-gate buffer, it serves as a fundamental building block for digital signal routing and isolation in complex integrated circuit designs.

Replacement Considerations

The SN74LVC1G125DBVTG4 is a verified substitute offering identical pinout and electrical characteristics but with active-low enable control instead of active-high. Other compatible options within the same package include variants from the 74LVC1G126 series with different suffixes indicating packaging or temperature variations.
