1 / 10 page © 1999 Fairchild Semiconductor Corporation DS009973 www.fairchildsemi.com November 1988 Revised October 1999 74AC573 • 74ACT573 Octal Latch with 3-STATE Outputs General Description 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. Features s ICC and IOZ reduced by 50% s Inputs and outputs on opposite sides of package allow- ing easy interface with microprocessors s Useful as input or output port for microprocessors s Functionally identical to 74AC373 and 74ACT373 s 3-STATE outputs for bus interfacing s Outputs source/sink 24 mA s 74ACT573 has TTL-compatible inputs Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Logic Symbols IEEE/IEC Connection Diagram Pin Descriptions FACT ™ is a trademark of Fairchild Semiconductor Corporation.
