74ALVT162241DL,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74ALVT162241 is a high-performance BiCMOS 16-bit inverting buffer/driver designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V. It features four independent Output Enables (1OE, 2OE, 3OE, 4OE), each controlling four 3-State outputs. The device incorporates 30Ω series resistance in both High and Low output stages to reduce line noise, overshoot, and undershoot, making it suitable for driving memory arrays. It includes bus-hold data inputs to eliminate external pull-up resistors.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 30Ω series termination resistors in output stages to minimize signal reflections and line noise without requiring external components.
• Bus-hold data inputs maintain logic states for unused pins, removing the need for external pull-up resistors.
• Power-up 3-State functionality ensures outputs remain in a high-impedance state during power transitions.
• Live insertion/extraction capability allows safe connection and disconnection while the system is powered.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type required for the design, as the component is available in 48-Pin Plastic SSOP Type III and 48-Pin Plastic TSSOP Type II configurations. Confirm that the selected variant meets the -40°C to +85°C operating temperature range requirements. Ensure the ordering suffix corresponds to the desired packaging format before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 2.5V or 3.3V systems with 5V buses due to its inherent voltage compatibility. The integrated termination resistors make it ideal for applications requiring controlled impedance on long traces. Consider the four independent enable lines if granular control over output groups is necessary for the specific bus architecture.
