74LVT162244MEAX

Overview

The onsemi 74LVT162244MEAX 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 an advanced BiCMOS technology for high-speed performance with low power dissipation. The device incorporates equivalent series resistance in the output stages to reduce overshoot, undershoot, and line noise without requiring external termination resistors. It supports nibble-controlled operation via four independent output enable inputs, which can be shorted for full 16-bit functionality.

Feature Summary

• Integrated equivalent series resistance in both HIGH and LOW output states eliminates the need for external termination resistors while reducing signal reflections.
• Provides glitch-free bus loading through Power Up/Power Down high impedance state, permitting live insertion and extraction.
• Supports TTL interface compatibility to 5V environments despite operating at low voltage (3.3V) supply levels.

Applications

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

Procurement Notes

This component is officially discontinued and not recommended for new designs by onsemi. Verify current availability status directly with authorized representatives or distributors, as stock may be limited or obsolete. Ensure compliance with RoHS requirements if applicable to your specific ordering suffix. Confirm package integrity upon receipt.

Selection Notes

Select this part only for legacy system maintenance or replacement where the specific integrated series resistance feature is required to simplify board layout. Evaluate functional compatibility with existing 74-series logic standards. Consider alternative modern buffers if new design implementation is possible, given the discontinued status.

Part Context

Originally manufactured by Fairchild Semiconductor before integration into onsemi, this device belongs to the LVT logic family designed for 3.3V applications. The MEAX suffix indicates the Small Shrink Outline Package (SSOP) variant with tape and reel packaging. It serves as a bridge between low-voltage logic and 5V tolerant systems.

Replacement Considerations

Verify pinout and electrical characteristics against potential substitutes from other manufacturers. Check for functional equivalence regarding the integrated series resistance and 3-STATE control logic. Consult official cross-reference lists for confirmed compatible replacements.
