74LVT162244MEA

Overview

The Fairchild Semiconductor 74LVT162244MEA is a low-voltage 16-bit buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V, utilizing LVTTL input levels and LVTTL output levels. The device provides high drive capability with a low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay is specified at 4.6 ns. It is housed in an SSOP-48 package and supports operation from -40°C to +85°C.

Feature Summary

• Provides non-inverting bidirectional buffering for bus-oriented applications
• Features 3-state outputs that disable ports to prevent bus loading during power-up or power-down
• Designed for live insertion and extraction without causing glitches

Applications

• Bus-oriented data transmission systems
• Memory interface circuits
• Microprocessor system interconnects

Procurement Notes

Verify the specific suffix 'MEA' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the component matches the required RoHS compliance status and operating temperature range for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a 16-bit unidirectional buffer with 3-state control is required for low-voltage logic interfaces. It serves as a functional replacement for standard 74 series drivers but requires a 3.3 V supply rail. Verify that the load capacitance requirements do not exceed the device's specified limits for the desired signal integrity.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage digital applications. It functions as a unidirectional buffer, distinct from transceivers like the 74LVTH162245 which offer bidirectional flow. The device is intended for high-speed data routing in systems requiring 3.3 V logic levels.

Replacement Considerations

Check for direct equivalents such as the 74LVT162244 from other manufacturers. Ensure pin compatibility and electrical characteristics match, particularly the 3-state enable logic and drive strength.
