74LVT162244MTD

Overview

The Fairchild Semiconductor 74LVT162244MTD is a low-voltage 16-bit buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.7V to 3.6V. The device utilizes advanced CMOS technology to achieve high-speed performance while maintaining low power dissipation. It is housed in a 48-pin TSSOP package, designed for bus-oriented applications requiring reliable signal transmission.

Feature Summary

• Provides non-inverting buffering for sixteen data lines with independent output enable control
• Supports direct interface between 5V systems and 3.3V systems through input tolerance
• Ensures glitch-free operation during power-up and power-down cycles

Applications

• High-density memory modules
• Clock distribution networks
• Bus-oriented system architectures

Procurement Notes

Verify the specific manufacturer designation as Fairchild Semiconductor or its successor entities like onsemi, given industry consolidation history. Confirm the package type matches the required 48-lead Thin Shrink Small Outline Package (TSSOP) dimensions. Ensure the logic family corresponds to Low-Voltage TTL (LVT) specifications for compatibility with existing 3.3V designs.

Selection Notes

Select this component when designing systems that require driving long buses or multiple loads at 3.3V logic levels. It serves as a suitable replacement for older ABT series drivers where lower voltage operation is necessary. Consider the pinout compatibility if migrating from similar 16-bit buffer families to ensure board layout adjustments are minimized.

Part Context

This part belongs to the LVT logic family, which bridges the gap between standard 5V TTL and modern low-voltage CMOS standards. It is functionally related to other 16-bit buffers but distinguished by its specific voltage thresholds and drive capabilities. The MTD suffix indicates the specific surface-mount packaging configuration used for automated assembly.

Replacement Considerations

Check for equivalents such as the NXP 74LVT162244 or Texas Instruments variants. Verify that substitute parts maintain the same 48-TSSOP footprint and electrical characteristics to avoid redesigning the host circuit board.
