74LVT162244MTD

Overview

The onsemi 74LVT162244MTD 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 utilizes a 48-lead Thin Shrink Small Outline Package (TSSOP). The device incorporates equivalent series resistance in the output stages to reduce overshoot and undershoot, eliminating the need for external termination resistors. It supports nibble-controlled operation with independent control inputs that can be shorted for full 16-bit functionality.

Feature Summary

• Integrated equivalent series resistance in both HIGH and LOW output states to minimize line noise and eliminate external termination requirements
• Capable of interfacing between low-voltage systems and 5V TTL environments while maintaining glitch-free bus loading during power-up or power-down
• Supports live insertion and extraction operations without causing bus current loading

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 availability through authorized representatives as standard distribution channels may no longer stock this part. Ensure compliance with end-of-life procedures and confirm updated ordering nomenclature if sourcing from legacy Fairchild Semiconductor inventory.

Selection Notes

Select this device for applications requiring 16-bit buffering with integrated output impedance control. Note that the 74LVTH162244 variant includes bushold data inputs, whereas the 74LVT162244 does not. Confirm package compatibility with the MTD48 TSSOP footprint and verify that the 2.7V to 3.6V operating range meets system voltage requirements.

Part Context

Part of the LVT logic family fabricated using advanced BiCMOS technology. Designed to provide high-speed performance comparable to 5V ABT devices while maintaining low power dissipation characteristics typical of low-voltage CMOS logic families.

Replacement Considerations

Verify functional equivalents such as the 74LVTH162244MTD which shares the same package but includes bushold inputs. Cross-reference with other 16-bit buffers in the LVT family ensuring pinout and electrical specifications match the original design constraints.
