SN74LVCZ240ANS

Gates And Inverters - Multi-Function, Configurable Overview

The SN74LVCZ240ANS is an octal buffer and line driver featuring three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 3.6V and supports input voltages up to 5.5V, ensuring compatibility with various logic families. The device provides a maximum propagation delay (tpd) of 6.5ns at 3.3V. At VCC = 3.3V and TA = 25°C, the output ground bounce (VOLP) is typically less than 0.8V. It is housed in a 20-SOIC package.

Gates And Inverters - Multi-Function, Configurable Feature Summary

• Provides eight buffered channels with independent control for data direction and output enablement.
• Features robust 5.5V tolerant inputs allowing safe interfacing with 5V logic systems while operating at lower core voltages.
• Includes power-up three-state functionality to prevent bus contention during system initialization.

• Clock distribution networks requiring low skew
• High-density microcontroller I/O expansion

Gates And Inverters - Multi-Function, Configurable Procurement Notes

Verify the specific suffix 'ANS' corresponds to the 20-SOIC package variant when sourcing. Confirm that the design requires 5.5V input tolerance if interfacing with legacy 5V components. Ensure the application voltage remains strictly within the 2.7V to 3.6V range to maintain specified electrical characteristics and avoid device damage.

Gates And Inverters - Multi-Function, Configurable Selection Notes

Select this component when low-voltage operation between 2.7V and 3.6V is required alongside high-speed performance. The 5.5V input tolerance makes it suitable for mixed-voltage environments. Consider the 6.5ns propagation delay for timing-critical paths. The SOIC-20 package offers a compact footprint for surface-mount assembly compared to through-hole alternatives.

Gates And Inverters - Multi-Function, Configurable Part Context

This part belongs to the LVCZ family, designed for low-voltage applications with enhanced noise immunity. Unlike standard LVC devices, the Z-series often includes specific improvements in output drive characteristics and ground bounce reduction. It serves as a direct replacement for older octal buffers in modern portable and battery-powered electronics where power efficiency is critical.

Gates And Inverters - Multi-Function, Configurable Replacement Considerations

Direct pin-compatible substitutes include other SN74LVCZ240 variants with different packaging options such as SN74LVCZ240ADWR or SN74LVCZ240APWR. Verify that alternative packages meet the thermal and mechanical requirements of the existing PCB layout.
