74LCXZ16244MTDX

Overview

The 74LCXZ16244MTDX is a digital integrated circuit belonging to the LCXZ series, manufactured by Fairchild Semiconductor. It functions as a 16-bit non-inverting buffer and line driver with three-state outputs. The device utilizes CMOS technology and operates within a supply voltage range of 2.3V to 3.6V. It features 5V tolerant inputs and outputs, allowing interface with 5V signal environments. The component is housed in a TSSOP package with 48 pins.

Feature Summary

• Provides sixteen non-inverting buffer channels with three-state output control for bus-oriented applications
• Features 5V tolerant inputs and outputs to facilitate interfacing between low-voltage logic and 5V systems
• Designed for low power dissipation while maintaining high-speed operation through advanced CMOS fabrication

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor's logic division was acquired by ON Semiconductor. Ensure the part number suffix matches the required tape-and-reel packaging configuration. Confirm RoHS compliance status and lead-free specifications against current datasheet revisions to guarantee regulatory adherence for modern manufacturing processes.

Selection Notes

Select this component when a 16-bit wide data path requires buffering with high-impedance state capability. It is suitable for designs needing compatibility between 3.3V or 2.5V logic domains and 5V peripherals. Consider the TSSOP package constraints and pin count relative to board space requirements compared to smaller channel counts.

Part Context

This part belongs to the LCXZ family of low-voltage CMOS logic devices. The LCXZ series is characterized by its ability to operate at reduced supply voltages while maintaining performance levels comparable to older standards. The specific model integrates sixteen channels, distinguishing it from octal variants like the 74LCX244.

Replacement Considerations

Compatible substitutes include the 74LCX244 for eight-channel applications or the 74VCXH16244 for similar 16-bit buffering with potentially different drive characteristics. Verify pinout compatibility and electrical specifications before substituting.
