Onsemi (MC74AC573DWG) Buffer / Line Driver, 74AC573, 2 V to 6 V, WSOIC-20

Product OverviewThe MC74AC573DWG is an octal Buffer/Line Driver with 3-state outputs. It is ahigh-speed octal latch with buffered common latch enable (LE) and bufferedcommon output enable inputs. It is functionally identical to the MC74AC373 buthas inputs and outputs on opposite sides. It contains eight D-type latches with3-state output buffer. When the latch enable (LE) input is HIGH, data on the Dninputs enters the latches. In this condition the latches are transparent, alatch output will change state each time its D input changes. When LE is LOW thelatches store the information that was present on the D inputs a setup timepreceding the HIGH-to-LOW transition of LE. The 3-state buffer is controlled bythe output enable (OE) input. When OE is LOW, the buffer is enabled. When OE isHIGH the buffer is in the high impedance mode but this does not interfere withentering new data into the latches.Inputs and outputs on opposite sides allowing easy interface withmicroprocessorsUseful as input or output port for microprocessors3-state Outputs for bus interfacingOutputs source/sink 24mATTL Compatible inputsProduct InformationLogic Family / Base Number: 74AC573Logic Device Type: Buffer, InvertingLogic Case Style: WSOICNo. of Pins: 20PinsSupply Voltage Min: 2VSupply Voltage Max: 6VLogic IC Family: 74ACLogic IC Base Number: 74573Operating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 3 - 168 hours
