SN74LVCZ240ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCZ240ANSR is an octal buffer with Schmitt-trigger inputs and 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 2.7V to 3.6V. The device features balanced CMOS outputs capable of sinking and sourcing similar currents, with a maximum propagation delay of 6.5ns at 3.3V. Inputs accept voltages up to 5.5V, supporting mixed-mode signal operation. It includes Ioff and power-up 3-state support for hot insertion.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt-trigger inputs provide noise filtering and stable switching characteristics.
• Balanced CMOS 3-state outputs allow for high-speed driving into light loads.
• Ioff circuitry disables outputs during partial power-down to prevent excessive current draw.
• Power-up 3-state feature ensures safe hot insertion without bus contention.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package marking and manufacturer logo against official Texas Instruments documentation to confirm authenticity. Ensure the ordering suffix matches the required package type (NS for SOP-20) and tape/reel specifications. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 3.3V logic buffering with Schmitt-trigger input noise immunity is required. It is suitable for applications needing mixed-mode signal operation where inputs tolerate 5.5V while VCC is 3.3V. Consider the 6.5ns propagation delay and output drive capabilities relative to load capacitance requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCZ240A family of octal buffers. It shares functional similarities with other LVC series devices but is distinguished by its specific 3.3V operating range and Schmitt-trigger input configuration. It serves as a high-speed interface solution between different logic domains.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down?

The device includes Ioff circuitry that disables all outputs when the supply pin is held at 0V, preventing excessive current flow regardless of input voltages.

What is the purpose of the Schmitt-trigger inputs?

The Schmitt-trigger inputs provide noise filtering, ensuring stable switching even with slow input transition rates or noisy signal environments.
