MC74LVX240DWR

Overview

The MC74LVX240DWR is an octal buffer and line driver manufactured by onsemi, belonging to the LVX logic series. It features eight inverting channels with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 3.6 V. Key electrical parameters include a propagation delay of 11 ns, high-level output current of -8 mA, low-level output current of 8 mA, and static current of 4 uA. It supports surface mount installation and functions reliably between -40°C and +85°C.

Feature Summary

• Provides eight inverting signal paths for bus driving applications
• Features three-state outputs to facilitate system isolation
• Utilizes CMOS technology for low power consumption

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffering
• Capacitive loading and line termination circuits

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the package type matches the design requirements. Ensure that the operating temperature range aligns with the intended application environment. Cross-reference the datasheet revision date to ensure access to the most current technical specifications and electrical characteristics.

Selection Notes

Select this component when an octal inverting buffer with three-state control is required for low-voltage digital systems. The LVX series offers compatibility with 3.3 V logic levels while maintaining performance at lower voltages down to 2 V. Consider the 20-pin SOIC package for standard PCB layouts requiring through-hole or surface-mount integration. Evaluate the 11 ns propagation delay against system timing constraints to ensure signal integrity is maintained across the bus.

Part Context

This part belongs to the MC74LVX family of high-speed CMOS logic devices produced by onsemi. The LVX series is designed for low-voltage applications, typically operating between 2 V and 3.6 V. It provides improved switching speeds and lower power consumption compared to older HC/HCT families. The MC74LVX240 variant specifically addresses the need for octal buffering in data communication and microprocessor-based systems.

Replacement Considerations

Compatible substitutes include the MC74LVX240MTC from onsemi in a TSSOP-20 package. Other manufacturers may offer equivalent parts such as the SN74LVX240 from Texas Instruments. Verify pinout compatibility and electrical specifications before substitution.
