Revised March 2005 74LVT2240 • 74LVTH2240 Low Voltage Inverting Octal Buffer/Line Driver with 3-STATE Outputs and 25: Series Resistors in the Outputs General Description Features 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: Series resistors helps reduce output overshoot and undershoot. ■ Input and output interface capability to systems at 5V VCC 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 capability 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 similar to 5V ABT while maintaining low power dissipation. ■ Equivalent 25: Series resistors on outputs ■ Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH2240), also available without bushold feature (74LVT2240) ■ Live insertion/extraction permitted ■ Power Up/Down high impedance provides glitch-free bus loading ■ Outputs source/sink 12 mA/12 mA ■ Latch-up performance exceeds 500 mA ■ ESD performance: Human-body model ! 2000V Machine model ! 200V Charged-device model ! 1000V Ordering Code: Order Number 74LVT2240WM 74LVT2240SJ Package Number 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide M20D Pb-Free 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74LVT2240MTC MTC20 74LVTH2240WM M20B 74LVTH2240SJ 74LVTH2240MTCX (Note 1) Package Description M20B M20D MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide Pb-Free 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.
