The MM74HC240 is an inverting octal 3-STATE buffer with two active LOW enables (1G and 2G). Each enable independently controls 4 buffers.
The document describes the MM74HC240 Inverting Octal 3-STATE Buffer, which utilizes advanced silicon-gate CMOS technology to achieve high-speed operation comparable to low power Schottky devices while maintaining high noise immunity and low power consumption. The device features two active LOW enables that independently control four buffers each.
