The 74AC573 and 74ACT573 are high-speed octal latches with buffered common Latch Enable (LE) and buffered common Output Enable (OE#) inputs. The 74AC573 and 74ACT573 are functionally identical to the 74AC373 and 74ACT373 but with inputs and outputs on opposite sides. Product Highlights: ICC and IOZ reduced by 50% Inputs and outputs on opposite sides of package allowing easy interface with microprocessors Useful as input or output port for microprocessors Functionally identical to 74AC373 and 74ACT373 3-STATE outputs for bus interfacing Outputs source/sink 24 mA 74ACT573 has TTL-compatible inputs
