1 / 6 page © 1999 Fairchild Semiconductor Corporation DS500212 www.fairchildsemi.com July 1999 Revised August 1999 74LVT2240 • 74LVTH2240 Low Voltage Inverting Octal Buffer/Line Driver with 3-STATE Outputs General Description The LVT2240 and LVTH2240 are inverting octal buffers and line drivers designed to be employed as memory address drivers, clock drivers and bus oriented transmitters or receivers which provides improved PC board density. The equivalent 25 Ω-Series resistors helps reduce output overshoot and undershoot. The LVTH2240 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These inverting octal buffers and line drivers are designed for low-voltage (3.3V) VCC applications, but with the capa- bility to provide a TTL interface to a 5V environment. The LVT2240 and LVTH2240 are fabricated with an advanced BiCMOS technology to achieve high speed operation simi- lar to 5V ABT while maintaining low power dissipation. Features s Input and output interface capability to systems at 5V VCC s Equivalent 25 Ω-Series resistors on outputs s Bushold data inputs eliminate the need for external pull- up resistors to hold unused inputs (74LVTH2240), also available without bushold feature (74LVT2240). 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 Ordering Code: Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
