Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering code matches the specific package requirements, as this component is available in a 48-Lead Thin Shrink Small Outline Package (TSSOP). Confirm if tape and reel packaging is required by checking for the 'X' suffix in the part number. Ensure compatibility with the specified operating temperature range of -40°C to +85°C for your intended environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit data buffering with inherent termination resistance to minimize signal reflections. It is suitable for applications needing 3.6V I/O tolerance despite lower core voltages. Consider the propagation delay specifications relative to your system clock speed and ensure proper pull-up resistor sizing for the OE pin during power transitions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ALVC logic family, characterized by low voltage operation and high speed. It serves as a specialized buffer solution compared to standard logic gates, specifically designed to handle bus-oriented transmission tasks. The integration of series resistors distinguishes it from basic buffers, offering built-in protection against line noise in high-speed digital interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for other 16-bit bus transceivers or buffers within the ALVC family. Verify pinout compatibility and electrical characteristics such as propagation delay and drive strength before substituting. Ensure any replacement maintains the 3.6V I/O tolerance and 3-STATE functionality required by the design.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused control inputs?

Unused control inputs must be held HIGH or LOW; floating inputs are not recommended to ensure stable operation.

What is the function of the OE_n input?

The Output Enable (OE_n) input controls the 3-STATE outputs. When LOW, outputs are active; when HIGH, they enter a high impedance state.
