NL17SZ126XV5T2G-L22087

Buffers, Drivers, Receivers, Transceivers Overview

The NL17SZ126XV5T2G is a single non-inverting buffer with 3-state output from the LCX logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and features inputs/outputs overvoltage tolerant up to 5.5 V. The device supports partial power down protection via IOFF. Typical propagation delay is 2.3 ns at 5 V, with maximum delays reaching 5.7 ns at 3.3 V and 5.0 ns at 5 V under specific capacitive loads. It provides source/sink currents of 24 mA at 3.0 V and is available in SC-88A, SC-74A-5, SOT-553-5, and SOT-953 packages.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package suffix matches the required form factor, as XV5 denotes SOT-553-5. Confirm the presence of the -Q suffix if automotive qualification or specific site control is mandated by the design specification. Ensure the ordering code includes the T2G designation for tape and reel shipping and RoHS compliance status before finalizing procurement documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single high-speed buffer with tri-state functionality is needed in a minimal footprint. The LCX technology offers fast switching speeds suitable for general-purpose digital interfaces. Consider the SOT-553-5 package for space-constrained layouts. Validate that the input signal levels align with the specified VIH and VIL thresholds across the intended operating temperature range.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE pin?

The OE (Output Enable) pin controls the state of the output Y. When OE is High, the output enters a high-impedance state. When OE is Low, the buffer functions normally, passing the input A to the output Y.

How does the IOFF feature benefit the circuit?

The IOFF feature prevents excessive current flow through the inputs or outputs when the device is powered down (VCC = 0 V). This allows connected components to remain powered while the buffer is off, protecting the system during partial power-down scenarios.
