The 74HC86D, 7486D, HC86D are contain four independent 2-input exclusive-OR gates. They perform the Boolean function Y = A B or Y = AB + A(B) in positive logic. A common application is as a true/complement element.
The SN74HC574N, SN74HCT574, SN74LS574N, SN74574 Are 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. The device features a clock (CP) and output enable (OE) inputs.
