MC74AC240DWR2G-Q

Overview

The MC74AC240DWR2G-Q is an octal buffer and line driver from the 74AC logic family, manufactured by onsemi. It features eight inverting outputs with three-state capability, housed in a 20-SOIC package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical specifications include a high-level output current of -24 mA and a low-level output current of 24 mA. Quiescent current is typically 8 µA, while operating supply current reaches 80 µA. It supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent inverting buffers or line drivers
• Three-state output control for efficient bus-oriented transmission applications
• Wide supply voltage operation supporting 2 V to 6 V ranges
• High drive capability with 24 mA output current sourcing and sinking

Applications

• Memory address driving systems
• Clock signal distribution networks
• Bus-oriented transmitter circuits

Procurement Notes

Verify the specific suffix 'Q' indicates automotive or qualified status requirements against the official datasheet. Confirm RoHS compliance details and moisture sensitivity levels prior to integration. Ensure the SOIC-20 package dimensions match the target PCB footprint. Validate that the 2V to 6V operating range aligns with the system power rails.

Selection Notes

Select this component when high-speed octal buffering with three-state control is required. The AC series offers faster propagation delays compared to standard 74LS equivalents. Consider the 24 mA drive strength for heavy capacitive loads. Verify compatibility with the system's logic voltage levels and thermal management needs for the SOIC-20 package.

Part Context

This part belongs to the MC74AC240 family of octal buffers. It is designed for memory address and clock driving applications. The device utilizes silicon gate CMOS technology. It serves as a bus-oriented transmitter in digital systems. The Q suffix typically denotes qualification standards beyond standard commercial grades.

Replacement Considerations

Check for MC74AC240DW without the Q suffix if qualification is not required. Verify pinout compatibility with other 74AC240 variants. Ensure equivalent drive strength and speed characteristics are maintained during substitution.
