74HC244 Octal Buffer Line Driver IC - DIP-20 Package Programmer 5V opens up a wideThe 74HC244 is an 8 bit buffer line driver with 3 state outputs. The device can be used as two 4 bit buffers or one 8 bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3 state outputs. A HIGH on OE causes the outputs to assume a high impedance OFF state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. A buffer is simply a unity
