OCTAL D-TYPE LATCH WITH 3-STATE OUTPUTS The MC74AC563/74ACT563 is a high-speed octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. The MC74AC563/74ACT563 device is functionally identical to the MC74AC573/ 74ACT573, but with inverted outputs. • Inputs and Outputs on Opposite Sides of Package Allowing Easy Interface with Microprocessors • Useful as Input or Output Port for Microprocessors • Functionally Identical to MC74AC573/74ACT573 but with Inverted Outputs • Outputs Source/Sink 24 mA • ′ACT563 Has TTL Compatible Inputs VCC O0 O1 O2 O3 O4 O5 O6 O7 LE 20 19 18 17 16 15 14 13 12 11 N SUFFIX CASE 738-03 PLASTIC DW SUFFIX CASE 751D-04 PLASTIC 1 2 3 4 5 6 7 8 9 10 OE D0 D1 D2 D3 D4 D5 D6 D7 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 FACT DATA 5-1 MC74AC563 MC74ACT563 FUNCTIONAL DESCRIPTION The MC74AC563/74ACT563 contains eight D-type latches with 3-state complementary outputs. When the Latch Enable (LE) input is HIGH, data on the D n 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 in the bi-state mode. When OE is HIGH the buffers are in the high impedance mode but that does not interfere with entering new data into the latches.
