SN74LV126ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV126ANSR is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode voltage operation on all ports. The device features independent line drivers where each output is disabled when the associated output-enable (OE) input is low. It provides maximum propagation delay of 6.5ns at 5V and typical output ground bounce of 2.3V at VCC = 3.3V. The component includes Ioff support for live insertion, partial power down mode, and back drive protection, with latch-up performance exceeding 250mA per JESD 17.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and pin configuration against the datasheet before procurement. Confirm that the ordering suffix matches the required tape and reel specifications. Ensure compatibility with the intended operating temperature range and voltage levels. Check for any recent documentation updates or revision history changes that may affect design implementation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring bus buffering with 3-state outputs in mixed-voltage environments. Consider its wide operating voltage range and low drive characteristics for minimizing output ringing. Evaluate the propagation delay and noise characteristics against system timing requirements. Ensure proper handling of unused inputs to prevent undefined operational states.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the SN74LV126ANSR handle partial power down mode?

The device supports partial power down mode through its Ioff feature, which prevents back drive current flow when the device is powered down but the system is active.

What is the function of the OE input pin?

The OE (Output Enable) input controls the state of the outputs. When OE is low, all outputs are disabled and enter a high-impedance state. When OE is high, the respective gate passes data from the A input to the Y output.
