| MC54/74F533 OCTAL TRANSPARENT LATCH WITH 3-STATE OUTPUTS The MC54 / 74F533 consists of eight latches with 3-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. For description and logic diagram please see the F373 data sheet.
