74LVT16244MEAX

Overview

The Fairchild Semiconductor 74LVT16244MEAX is a low-voltage 16-bit buffer and line driver featuring three-state outputs. Designed for high-speed data transmission, it operates within a supply voltage range of 2.5V to 3.3V. The device utilizes advanced CMOS technology to achieve low power consumption while maintaining high noise immunity. It includes separate output enable controls for each nibble, allowing flexible bus-oriented applications. The component is housed in a 48-pin TSSOP package suitable for surface-mount assembly.

Feature Summary

• Provides sixteen non-inverting buffers with independent three-state control for each nibble
• Operates at low supply voltages of 2.5V or 3.3V for reduced power dissipation
• Features high noise immunity and latch-up performance exceeding industry standards
• Supports live insertion and withdrawal capabilities without system damage

Applications

• Memory address and data bus drivers in computer systems
• Clock distribution networks requiring low skew and high drive capability
• Bus-oriented transmitter and receiver circuits in embedded systems
• High-speed digital signal routing between mixed-voltage logic domains

Procurement Notes

Verify the specific manufacturer source as Fairchild Semiconductor has undergone corporate restructuring. Confirm current availability through authorized distributors or ON Semiconductor channels, as legacy part numbers may have superseded status. Ensure the datasheet revision matches your design requirements for electrical characteristics and pinout compatibility before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring 16-bit wide data paths with low voltage operation. It is suitable for replacing older LVC series devices where lower supply voltage is required. Consider the TSSOP-48 package constraints regarding thermal management and PCB space. Verify that the input voltage levels are compatible with the driving logic family to ensure reliable switching thresholds across the operating temperature range.

Part Context

This part belongs to the 74LVT logic family, which is optimized for 3.3V systems. It serves as a bridge between 3.3V logic blocks and other peripheral interfaces. The 16244 designation indicates a non-inverting buffer configuration. Similar parts in the series include the 74LVC16244 for 3.3V/5V tolerance and the 74ALVT16244 for higher speed performance at 3.3V.

Replacement Considerations

Check for equivalents from ON Semiconductor, such as the 74LVT16244MTCX, which shares identical functionality and pinout. Verify that any substitute maintains the same VFBGA or TSSOP package dimensions if board space is constrained. Ensure the replacement supports the same 2.5V to 3.3V operating range and three-state control logic.
