MC74VHCT240ADWR2G

Overview

The MC74VHCT240ADWR2G is an octal inverting buffer and line driver from the VHCT logic family, manufactured by onsemi. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides high-level output current of -8 mA and low-level output current of 8 mA. It exhibits a propagation delay of 6.1 ns and consumes 1.35 mA of static current. The component is housed in a 20-SOIC package and supports surface mount installation. It functions across a temperature range of -40°C to +85°C.

Feature Summary

• Octal configuration with three-state outputs for bus-oriented applications
• TTL-compatible input levels via VHCT technology
• Inverting buffer and line driver functionality

Applications

• Bus-oriented memory and address drivers
• Clock drivers
• Buffering applications requiring TTL-to-CMOS translation

Procurement Notes

Verify the specific suffix 'ADWR2G' against official datasheets to confirm RoHS compliance and lead-free status. Confirm the SOIC-20 package dimensions match design constraints. Ensure the VHCT series specifications align with system voltage requirements before procurement.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS outputs in a 5 V environment. The VHCT series offers faster switching speeds compared to standard HC or HCT families. Verify that the 8 mA drive capability meets load requirements for connected circuitry.

Part Context

This part belongs to the MC74VHCT240A series of octal buffers. It is designed for high-speed digital applications requiring interface between TTL and CMOS logic levels. The device is widely used in computing and industrial control systems where signal integrity and speed are critical.

Replacement Considerations

Direct substitutes include other VHCT octal inverters with identical pinouts and electrical characteristics. Cross-reference with similar parts from other manufacturers ensuring matching voltage ranges and package types.
