The 'F533 consists of eight latches with TRI-STATE outputs for bus organized system applications. The flip-flops appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup times is latched. Data appears on the bus when the Output Enable (OE#) is LOW. When OE# is HIGH the bus output is in the high impedance state. The 'F533 is the same as the 'F373, except that the outputs are inverted.
