74LVQ240QSC

Overview

The onsemi 74LVQ240QSC is an inverting octal buffer and line driver featuring 3-STATE outputs, designed for memory address, clock, and bus applications. It operates within a supply voltage range of 2.0V to 3.6V and supports an operating temperature from -40°C to +85°C. The device provides ±12mA output drive current with propagation delays up to 15.0ns at 3.3V. It utilizes a 20-Lead Quarter Size Outline Package (QSOP) and incorporates patented EMI reduction circuitry.

Feature Summary

• Patented EMI reduction circuitry for low noise performance
• Guaranteed incident wave switching into 75Ω transmission lines
• High latch-up immunity and 4kV minimum ESD protection

Applications

• Memory address drivers
• Clock drivers
• Bus oriented transmitters or receivers

Procurement Notes

Verify the specific QSOP package variant against the datasheet M20B/MQA20 designation. Confirm that the component meets the required logic levels and environmental specifications for the target application before integration.

Selection Notes

Select this component for designs requiring low power consumption and improved PC board density. Ensure the system voltage remains within the 2.0V to 3.6V range and consider the 3-STATE control inputs for bus management.

Part Context

This part belongs to the LVQ series of low-voltage CMOS logic devices. It serves as an octal buffer/driver alternative to standard voltage logic families, offering enhanced performance in 3.3V environments while maintaining compatibility with various digital interfaces.

Replacement Considerations

Check for direct pin-compatible substitutes within the same logic family. Verify that any replacement maintains the 3-STATE functionality and similar propagation delay characteristics.
