Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm active status and material composition. Ensure the selected variant matches the required thermal performance and moisture sensitivity level for the intended assembly process. Cross-reference the datasheet revision history to validate that the documentation aligns with the specific production lot characteristics.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing bus interfaces requiring low-drive CMOS technology to minimize output ringing and overshoot. It is suitable for applications needing voltage translation from 5.5V tolerant inputs to lower VCC levels. Consider the operating temperature range and ESD ratings to ensure compatibility with the system environment and handling requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV126A family of quadruple bus buffer gates. It shares functional similarities with other LV series logic devices but is distinct in its specific 3-state buffering configuration. The device is designed for high-density applications where space-saving packages like TVSOP are preferred over larger footprints.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power down mode?

The integrated Ioff circuitry prevents current flow through the inputs or outputs when the device is powered down, supporting safe partial power down modes.

What is the function of the OE input pin?

The Output Enable (OE) input controls the state of the buffers; when OE is low, the associated outputs are disabled and enter a high-impedance state.
