Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific RKS (VQFN) package variant when ordering, as the SN74AC244 family includes multiple package options such as SOIC, TSSOP, and SSOP. Confirm the active production status and lead finish details via the latest TI Package Option Addendum. Ensure design compliance with ESD handling precautions during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring wide voltage operation between 2V and 6V. The AC series offers faster switching speeds compared to standard LS or HC logic families. Consider the VQFN package for compact board layouts where thermal dissipation through the exposed pad is manageable.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4AC244 family of octal buffers and drivers. The 'AC' designation indicates advanced CMOS technology, providing higher speed and lower power consumption than previous generations. The device is organized into two independent 4-bit sections with separate output enable controls.

Buffers, Drivers, Receivers, Transceivers FAQ

How are the outputs controlled?

The device contains two 4-bit buffers with separate output-enable (OE) inputs. When OE is low, data passes from inputs to outputs; when high, outputs enter a high-impedance state.

What is the recommended handling for unused inputs?

All unused inputs must be held at VCC or GND to ensure proper device operation and prevent undefined states.
