74ALVT162244DL,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74ALVT162244 is a high-performance BiCMOS 16-bit buffer and line driver designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V. It features non-inverting 3-State bus outputs and includes integrated series resistance of 30Ω in both High and Low states, eliminating the need for external terminating resistors. The device supports live insertion/extraction and provides power-up 3-State functionality. It operates within a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 30Ω series output resistance reduces line noise without requiring external termination components
• Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
• Supports live insertion and extraction while preventing bus current loading when outputs are tied to a 5V bus
• Provides latch-up protection exceeding 500mA per JEDEC Std 17 and ESD protection exceeding 2000V per MIL STD 883 Method 3015

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type required for your design, as the component is available in 48-Pin Plastic SSOP Type III (SOT370-1) and 48-Pin Plastic TSSOP Type II (SOT362-1). Confirm that the operating voltage aligns with either the 2.5V or 3.3V recommended ranges. Ensure that the thermal environment does not cause junction temperatures to exceed 150°C during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 2.5V/3.3V logic systems and 5V I/O buses. The integrated 30Ω series resistance makes it suitable for applications requiring reduced line noise without additional external components. Consider the 48-pin SSOP or TSSOP packages based on board space constraints and mounting preferences.
