1 / 7 page © 2005 Fairchild Semiconductor Corporation DS012170 www.fairchildsemi.com July 1999 Revised March 2005 74LVT2244 • 74LVTH2244 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs and 25 : Series Resistors in the Outputs General Description The LVT2244 and LVTH2244 are octal buffers and line drivers designed to be employed as memory address driv- ers, clock drivers and bus oriented transmitters or receivers which provides improved PC board density. The equivalent 25 :-Series resistors helps reduce output overshoot and undershoot. The LVTH2244 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These octal buffers and line drivers are designed for low- voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT2244 and LVTH2244 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation. Features s Input and output interface capability to systems at 5V VCC s Equivalent 25 :-Series resistors on outputs s Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH2244), also available without bushold feature (74LVT2244). s Live insertion/extraction permitted s Power Up/Down high impedance provides glitch-free bus loading s Outputs source/sink 12 mA/12 mA s Latch-up performance exceeds 500 mA s ESD performance: Human-body model ! 2000V Machine model ! 200V Charged-device model ! 1000V Ordering Code: Devices also available in Tape and Reel. Specify by appending the 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.
