| MC74AC573 MC74ACT573 Octal D Type Latch with 3 State Outputs The MC74AC573/74ACT573 is a high-speed octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. The MC74AC573/74ACT573 is functionally identical to the MC74AC373/ 74ACT373 but has inputs and outputs on opposite sides. * Inputs and Outputs on Opposite Sides of Package Allowing Easy Interface with Microprocessors * Useful as Input or Output Port for Microprocessors * Functionally Identical to MC74AC373/74ACT373 * 3-State Outputs for Bus Interfacing * Outputs Source/Sink 24 mA * ACT573 Has TTL Compatible Inputs VCC 20 O0 19 O1 18 O2 17 O3 16 O4 15 O5 14 O6 13 O7 12 LE 11 OCTAL D-TYPE LATCH WITH 3-STATE OUTPUTS N SUFFIX CASE 738-03 PLASTIC DW SUFFIX CASE 751D-04 PLASTIC 1 OE 2 D0 3 D1 4 D2 5 D3 6 D4 7 D5 8 D6 9 D7 10 GND LOGIC SYMBOL PIN NAMES D0-D7 LE OE O0-O7 Data Inputs Latch Enable Input 3-State Output Enable Input 3-State Latch Outputs D0 D1 D2 D3 D4 D5 D6 D7 LE OE O0 O1 O2 O3 O4 O5 O6 O7 Outputs Dn H L X X On H H O0 Z TRUTH TABLE Inputs OE L L L H LE H H L X H = HIGH Voltage Level L = LOW Voltage Level Z = High Impedance X = Immaterial O0 = Previous O0 before LOW-to-HIGH Transition of Clock FACT DATA 5-1 MC74AC573 MC74ACT573 FUNCTIONAL DESCRIPTION The MC74AC573/74ACT574 contains eight D-type latches with 3-state output buffers. When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D input changes. When LE is LOW the latches store the information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-state buffers are controlled by the Output Enable (OE) input. When OE is LOW, the buffers are enabled. When OE is HIGH the buffers are in the high impedance mode but this does not interfere with entering new data into the latches.
