1 / 8 page © 2005 Fairchild Semiconductor Corporation DS012450 www.fairchildsemi.com March 1999 Revised March 2005 74LVT573 • 74LVTH573 Low Voltage Octal Transparent Latch with 3-STATE Outputs General Description The LVT573 and LVTH573 consist of eight latches with 3-STATE outputs for bus organized system applications. The latches appear transparent to the data when Latch Enable (LE) is HIGH. When LE is low, the data satisfying the input timing requirements is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the bus output is in the high impedance state. The LVTH573 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These octal latches are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT573 and LVTH573 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation. Features s Input and output interface capability to systems at 5V VCC s Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH573), also available without bushold feature (74LVT573) s Live insertion/extraction permitted s Power Up/Down high impedance provides glitch-free bus loading s Outputs source/sink 32 mA/64 mA s Functionally compatible with the 74 series 573 s Latch-up performance exceeds 500 mA s ESD performance: Human-body model ! 2000V Machine model ! 200V Charged-device model ! 1000V Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Pb-Free package per JEDEC J-STD-020B. Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
