MC74AC533

www.DataSheet4U.com MC74AC533 MC74ACT533 Octal Transparent Latch with 3ĆState Outputs The MC74AC533/74ACT533 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 time 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 ′AC/ACT533 is the same as the ′AC/ACT373, except that the outputs are inverted. For description and logic diagram please see the ′AC/ACT373 data sheet.
