74LCX126MTCX

Overview

The 74LCX126MTCX is a low-voltage quad buffer with 5V tolerant I/O manufactured by onsemi. It operates within a supply voltage range of 2V to 3.6V and features non-inverting logic with tri-state outputs. The device utilizes a 14-pin TSSOP surface-mount package. Key electrical characteristics include high-level output current of -24mA and low-level output current of 24mA, with a maximum static current of 10µA. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides four independent non-inverting buffer channels with tri-state control for bus-oriented communication.
• Features 5V tolerant inputs allowing direct interfacing between 3.3V systems and 5V peripherals without level shifting.
• Incorporates proprietary noise/EMI suppression circuitry to enhance signal integrity in high-speed digital applications.

Applications

• Bus-oriented architectures requiring controlled signal transmission
• Clock buffering and distribution networks
• Data acquisition systems utilizing mixed voltage domains

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration. Confirm RoHS compliance status and material declarations prior to integration. Cross-reference the component marking code with the latest production notices to validate authenticity and manufacturing origin.

Selection Notes

Select this component when designing circuits that require low-voltage operation combined with 5V input tolerance. Ensure the application demands tri-state functionality for bus sharing. Verify that the required drive current aligns with the specified ±24mA limits and that the thermal environment remains within the industrial temperature range.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. It serves as a buffer solution within the broader 74-series logic ecosystem, specifically optimized for modern low-power portable electronics and communication equipment where voltage translation between different logic families is necessary.

Replacement Considerations

Check for cross-manufacturer equivalents such as MM74LCX126MTCX or MC74LCX126MTCX. Verify pinout compatibility and electrical specifications before substitution. Ensure any alternative maintains the same 14-TSSOP package dimensions and tri-state output characteristics.
