74LVT162244MEA

Overview

The onsemi 74LVT162244MEA is a discontinued low-voltage 16-bit buffer and line driver featuring 3-STATE outputs. It operates within a supply voltage range of 2.7V to 3.6V and supports input voltages up to 5.5V, enabling TTL interface compatibility with 5V systems. The device utilizes an advanced BiCMOS technology for high-speed operation while maintaining low power dissipation. It is housed in a 48-Lead Small Shrink Outline Package (SSOP).

Feature Summary

• Integrated equivalent series resistance in output drivers to reduce overshoot, undershoot, and line noise without requiring external termination resistors.
• Nibble-controlled architecture allowing independent control of four-bit segments or combined 16-bit operation via shorted control pins.
• Power-up and power-down high-impedance state ensures glitch-free bus loading during system initialization.
• Live insertion and extraction permitted, supporting hot-swapping applications.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitters and receivers

Procurement Notes

This component is officially discontinued and not recommended for new designs. Verify current availability status through authorized distributors or contact the manufacturer directly for legacy support information. Ensure compliance with RoHS requirements if sourcing remaining stock from secondary markets.

Selection Notes

Select this part only for existing maintenance or replacement scenarios due to its discontinued status. Consider functional equivalents if designing new hardware. Verify package dimensions against PCB footprints, specifically the 48-Lead SSOP form factor. Confirm electrical compatibility with 3.3V logic levels and 5V tolerant inputs.

Part Context

Part of the LVT logic family designed for low-voltage applications. Originally manufactured by Fairchild Semiconductor before integration into ON Semiconductor. Functionally compatible with standard 74-series 162244 devices but optimized for lower voltage operation and reduced power consumption.

Replacement Considerations

Contact onsemi representatives for updated substitute options as the device is discontinued. No specific public substitute part numbers are confirmed in the provided documentation.
