74LVQ244QSC

Overview

The onsemi 74LVQ244QSC is a low voltage octal buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.0V to 3.6V and supports an operating temperature range from -40°C to +85°C. The device utilizes a 20-lead Quarter Size Outline Package (QSOP). Key electrical characteristics include a propagation delay of up to 14.0 ns at 2.7V, maximum output current of ±12 mA, and quiescent supply current of 40 µA.

Feature Summary

• Implements patented EMI reduction circuitry for signal integrity
• Guarantees simultaneous switching noise level and dynamic threshold performance
• Provides improved latch-up immunity compared to standard logic families

Applications

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

Procurement Notes

Verify the specific package variant QSOP against the datasheet ordering code MQA20. Confirm that the component meets the required environmental specifications for the intended operating temperature range. Ensure compatibility with the target system's voltage levels and input/output requirements before finalizing procurement.

Selection Notes

Select this component when low power consumption and reduced electromagnetic interference are critical design constraints. The guaranteed incident wave switching capability makes it suitable for transmission line applications. Consider the physical dimensions of the QSOP package to ensure adequate board space availability during layout planning.

Part Context

This component belongs to the LVQ series of low voltage logic devices designed for high-density PCB applications. It serves as an octal buffer providing non-inverting functionality with three-state control inputs. The device is engineered to interface between different logic families while maintaining signal integrity in noisy environments.

Replacement Considerations

Check for direct equivalents such as the 74LVX244 or 74LVT244 variants if pinout compatibility is required. Verify that any substitute maintains the same 3-state output configuration and voltage operating ranges. Ensure the replacement package matches the existing footprint or allows for necessary adapter modifications.
