74LVT162240MTD

Overview

The Fairchild Semiconductor 74LVT162240MTD is a low-voltage 16-bit bus driver featuring three-state outputs, housed in a 48-lead TSSOP package. It operates within a supply voltage range of 3.0V to 3.6V and supports an operating temperature from -40°C to +85°C. The device provides high-speed performance with a propagation delay of 5.5ns at 3.3V and 50pF load, while maintaining low power dissipation typical of CMOS technology.

Feature Summary

• Provides sixteen non-inverting bidirectional buffers with three-state outputs for bus-oriented applications
• Features input and output interface capability compatible with 5V systems despite lower supply voltage operation
• Includes bus-hold data inputs to eliminate the need for external pull-up resistors on unused inputs

Applications

• High-density memory mapping
• Clock drivers
• Bus-oriented architectures requiring 16-bit data transfer

Procurement Notes

Verify the specific suffix 'MTD' against official datasheets to confirm pinout and package dimensions match your PCB footprint requirements. Ensure the component meets RoHS compliance standards if required by your manufacturing process. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select this component when designing systems that require 16-bit wide data paths with low voltage logic levels. It is suitable for applications needing interface between 3.3V logic and 5V tolerant peripherals. Consider the TSSOP-48 package constraints regarding thermal management and board space compared to alternative packages like FBGA.

Part Context

This part belongs to the LVT (Low Voltage TTL) family, designed for high-speed digital applications. It is functionally similar to other 16-bit bus drivers but optimized for lower voltage operation. The series is widely used in consumer electronics and industrial control systems where power efficiency and speed are critical factors.

Replacement Considerations

Check for direct replacements such as the 74LVTH162240 or equivalent parts from other manufacturers offering identical pinouts and electrical characteristics. Ensure any substitute maintains the same bus-hold functionality and three-state output capabilities.
