MC74HC240ADTR2G-Q

Overview

The MC74HC240ADTR2G-Q is an octal 3-state inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature from -55°C to +125°C. The device features two active-low output enables and provides high noise immunity characteristic of CMOS devices. Propagation delays vary with voltage, ranging from 80 ns at 2.0 V to 14 ns at 6.0 V. It is housed in a TSSOP-20 package and is AEC-Q100 qualified.

Feature Summary

• AEC-Q100 qualified for automotive applications
• PPAP capable manufacturing process
• High noise immunity typical of CMOS technology
• Direct interface capability with CMOS, NMOS, and TTL logic families

Applications

• 3-state memory address drivers
• Clock drivers
• Sub-oriented systems requiring bus holding

Procurement Notes

Verify the specific suffix 'Q' indicates compliance with unique site and control change requirements mandated by automotive standards. Confirm that PPAP capability is required for the intended application environment. Ensure the ordering information matches the exact package type and tape-and-reel specifications provided in the official documentation.

Selection Notes

Select this component when an octal inverting buffer with 3-state outputs is required for high-speed digital interfaces. The HC series offers compatibility with standard CMOS outputs and LSTTL outputs when pull-up resistors are utilized. Consider the wide operating voltage range and extended temperature capabilities for robust system design.

Part Context

This part belongs to the MC74HC240A family of octal buffers. It shares identical pinouts with LS240 equivalents but utilizes high-performance silicon-gate CMOS technology. The '-Q' designation specifically denotes qualification for automotive and other demanding environments requiring strict quality control changes.
