Octal Buffer Line Driver IC - 74HC240
The 74HC series 74HC240 3-STATE buffer utilizes advanced silicon-gate CMOS technology. It possesses high drive current outputs which enable high-speed operation even when driving large bus capacitances. These circuits achieve speeds comparable to low-power Schottky devices while retaining the advantage of CMOS circuitry, i.e., high noise immunity and low power consumption. It has a fanout of 15 LS-TTL equivalent inputs.
The 74HC240 is an inverting buffer and has two active LOW enables (1G and 2G). Each enables independent controls with 4 buffers. All inputs are protected from damage due to static discharge by diodes to VCC and the ground.
