74LCXZ162244MTD

Overview

The 74LCXZ162244MTD is a low voltage 16-bit buffer and line driver manufactured by Fairchild Semiconductor. It features non-inverting logic with 3-state outputs, designed for memory, address, and clock driving applications. The device operates within a supply voltage range of 2.3V to 3.6V and supports live insertion/withdrawal due to its high-impedance power-down state. It incorporates patented noise and EMI reduction circuitry to minimize signal interference. The component is housed in a 48-TSSOP package and offers 5V tolerant inputs and outputs, ensuring compatibility with mixed-voltage systems.

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor operations have transitioned to ON Semiconductor. Confirm that the 74LCXZ162244MTD designation aligns with current product portfolios, noting potential status changes or obsolescence. Ensure the package type matches the required 48-TSSOP form factor and validate RoHS compliance documentation for the specific production batch before procurement.

Selection Notes

Select this component when designing low-voltage digital systems requiring 16-bit data buffering with 5V tolerance. It is suitable for applications needing reduced electromagnetic interference and support for hot-swapping environments. Consider the 2.3V to 3.6V operating range and the 48-pin TSSOP package constraints during PCB layout. Verify that the nibble-controlled 3-state functionality meets the specific bus control requirements of the target design.

Part Context

This part belongs to the 74LCXZ series, which represents low-voltage CMOS logic technology optimized for high-speed performance and low power consumption. The LCXZ variant specifically emphasizes 5V tolerance, allowing safe interfacing between 3.3V logic devices and legacy 5V components. This series is widely used in portable electronics and communication equipment where power efficiency and signal integrity are critical design parameters.

Replacement Considerations

The 74LCX162244GX is a documented similar part from the same manufacturer family. Verify functional equivalence regarding pinout and electrical characteristics before substitution. Note that the base product number 74LCXZ162244 may have superseded older revisions, so confirm current availability and datasheet alignment.
