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.

ADDITIONAL RESOURCES
1.What is the function of the 74HC240 IC?
- The 74HC240 integrated circuit is an octal buffer/line driver with three output states. It is commonly used to drive LEDs, displays, and other output devices in digital circuits.
2.How is the 74HC240 different from the 74HC244 IC?
- The 74HC240 and 74HC244 are both octal buffer/line driver ICs with three-state outputs, but their functions differ. The 74HC240 is a non-inverting buffer, which means that the output pins always follow the input pins. The 74HC244 is an inverting buffer, which means that its output pins are the complement of its input pins. The 74HC244 also has two additional input pins, allowing it to be used in a bi-directional bus system.
