Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'ZRDR' corresponds to the required package type and lead finish before procurement. Confirm that the Pb-free designation aligns with project environmental compliance requirements. Ensure the operating temperature range of -40 °C to 85 °C meets the application's thermal specifications. Cross-reference the datasheet revision date to ensure compatibility with existing design documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide data path requires high-speed buffering with low power consumption in the ALVC series. It is suitable for applications needing operation down to 1.65 V. Consider the 3 ns propagation delay for timing-critical designs. Verify that the 3-state output configuration matches the bus architecture requirements. Evaluate the package options if space constraints differ from the standard reel packaging.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALVC16244A family, which includes variants like SN74ALVC16244ADGGR and SN74ALVC16244ADLR. These devices share the same core logic function but differ in package types such as TSSOP, SSOP, and FBGA. The family is characterized by its ability to operate across a wide voltage range while maintaining fast switching speeds.

Buffers, Drivers, Receivers, Transceivers FAQ

How should unused OE inputs be handled during power up or power down?

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor.

What is the maximum propagation delay specified for this device?

The maximum propagation delay is 3 ns at 3.3 V.
