74LVT2244 • 74LVTH2244 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs and 25Ω Series Resistors in the Outputs July 1999 Revised November 2000 74LVT2244 74LVTH2244 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs and 25Ω Series Resistors in the Outputs General Description Features The LVT2244 and LVTH2244 are octal buffers and lineInput and output interface capability to systems at drivers designed to be employed as memory address driv- 5V V CC ers, clock drivers and bus oriented transmitters or receivers Equivalent 25Ω-Series resistors on outputs which provides improved PC board density. The equivalent Bushold data inputs eliminate the need for external 25Ω-Series resistors helps reduce output overshoot and pull-up resistors to hold unused inputs (74LVTH2244), undershoot. also available without bushold feature (74LVT2244). The LVTH2244 data inputs include bushold, eliminating the Live insertion/extraction permitted need for external pull-up resistors to hold unused inputs. Power Up/Down high impedance provides glitch-free These octal buffers and line drivers are designed for low- bus loading voltage (3.3V) V applications, but with the capability to CC Outputs source/sink −12 mA/+12 mA provide a TTL interface to a 5V environment. The LVT2244 Latch-up performance exceeds 500 mA and LVTH2244 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5VESD performance: ABT while maintaining low power dissipation.
