74LCX126FT

Overview

The 74LCX126FT is a quad buffer manufactured by Toshiba Semiconductor and Storage, belonging to the 74LCX logic family. It features four non-inverting buffers with three-state outputs housed in a 14-TSSOP package. The device operates within a supply voltage range of 1.65V to 3.6V. Each buffer element provides high-level and low-level output currents of 24mA. The component supports surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Quad configuration providing four independent non-inverting buffer channels
• Three-state output capability for bus-oriented communication control
• High drive strength delivering 24mA output current at both logic levels
• Low voltage operation optimized for 1.65V to 3.6V power supplies

Applications

• Bus-oriented memory and signal driving applications
• Clock buffering and distribution circuits
• Data acquisition systems requiring signal isolation
• Portable equipment utilizing low voltage power sources

Procurement Notes

Verify the manufacturer part number 74LCX126FT against official Toshiba documentation to confirm specifications. Ensure the 14-TSSOP package type matches design requirements. Confirm the 1.65V to 3.6V operating voltage range aligns with system power rails. Validate the -40°C to +85°C industrial temperature rating for environmental suitability before integration.

Selection Notes

Select this component when designing systems requiring low voltage CMOS logic with high drive capability. The 24mA output current supports direct driving of loads without additional amplification. The three-state feature enables efficient bus sharing in multi-driver environments. Consider the 14-TSSOP footprint for compact surface-mount layouts compatible with standard automated assembly processes.

Part Context

This buffer belongs to the 74LCX series, which utilizes CMOS technology for low power consumption and high speed performance. The LCX family is designed for compatibility with 3.3V systems while maintaining pinout compatibility with older 5V logic families. This specific model provides buffered signal paths with controlled impedance characteristics suitable for digital interface applications.
