The MC14503B is a hex non–inverting buffer with 3–state outputs, and a high current source and sink capability. The 3–state outputs make it useful in common bussing applications. Two disable controls are provided. A high level on the Disable A input causes the outputs of buffers 1 through 4 to go into a high impedance state and a high level on the Disable B input causes the outputs of buffers 5 and 6 to go into a high impedance state.
