74LVC1G126GM,132

Overview

The Nexperia 74LVC1G126GM,132 is a single bus buffer and line driver featuring a three-state output, housed in an XSON6 (SOT886) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports overvoltage tolerant inputs up to 5.5 V. The device provides ±24 mA output drive at VCC = 3.0 V and includes IOFF circuitry for partial power-down mode operation. It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36, ensuring direct interface compatibility with TTL levels.

Feature Summary

• Features Schmitt-trigger action at all inputs to ensure tolerance for slower input rise and fall times.
• Includes IOFF circuitry that disables the output to prevent potentially damaging backflow current during partial power-down applications.
• Provides high noise immunity and CMOS low power dissipation characteristics.

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Partial power-down mode operations requiring backflow current prevention
• Interfaces requiring direct connection to TTL level devices

Selection Notes

Select this component when a single-channel non-inverting buffer with three-state control is required in space-constrained designs. The XSON6 package offers a compact footprint suitable for portable electronics. Ensure the application voltage falls within the 1.65 V to 5.5 V range and consider the IOFF feature if partial power-down functionality is necessary to protect downstream components from backflow currents.

Part Context

This part belongs to the 74LVC family of logic ICs, which are designed for low-voltage CMOS applications. The 74LVC1G126 series specifically focuses on single-buffer configurations with enhanced drive capabilities and robust ESD protection. It is manufactured by Nexperia USA Inc. and is available in multiple package options, including TSSOP5, SC-74A, and various XSON variants, catering to different PCB layout requirements.

Replacement Considerations

Check for pin-compatible alternatives such as the 74LVC1G125 series, which shares similar functional characteristics but may differ in specific electrical parameters or package availability. Verify that any substitute maintains the same three-state output behavior and voltage tolerance specifications.

FAQ

What is the function of the IOFF circuitry in the 74LVC1G126?

The IOFF circuitry disables the output when the device is powered down, preventing potentially damaging backflow current through the device.

Can the 74LVC1G126 interface directly with TTL levels?

Yes, the device is specified for direct interface with TTL levels due to its input voltage thresholds and noise immunity characteristics.
