Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' corresponds to the extended temperature rating of -40°C to 125°C rather than the standard industrial range. Confirm the PW package designation indicates the TSSOP form factor. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications and electrical characteristics tables.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-density bus-oriented receivers or transmitters. The dual 4-bit organization with separate output enables allows flexible control of data flow. Ensure the system logic levels match the HC series requirements and that the PCB layout accommodates the fast edge rates to prevent ringing on light loads.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4HC244 family of octal buffers and line drivers. It is designed to improve performance and density in 3-state memory address drivers and clock drivers. The device consists of two independent 4-bit buffers with separate output-enable inputs for precise signal management.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE pins?

The OE (Output Enable) pins control the state of the outputs. When low, the device passes noninverted data from inputs to outputs; when high, the outputs enter a high-impedance state.

How are the buffers organized internally?

The device is organized as two 4-bit buffers and drivers, each with its own separate output-enable input.
