M54HC7240/7241/7244 M74HC7240/7241/7244 are high performance CMOS eight-way buffers with strong output drive capability, high noise immunity, symmetric output current, symmetric delays, wide operating voltage range and other features.
This document is a datasheet for the SGS-THOMSON M54HC7240, M54HC7241, and M54HC7244 series of high-speed CMOS octal bus buffers. These devices feature silicon gate C2MOS technology, combining the high speed of LSTTL with low power consumption. They are available in inverted (HC7240) and non-inverted (HC7241/7244) output configurations and are pin and function compatible with 54/74LS240/241/244 series devices.
