74LVT240, 74LVTH240 — Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs January 2008 74LVT240, 74LVTH240 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs Features ■ Input and output interface capability to systems at ■ General Description The LVT240 and LVTH240 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 LVTH240 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 lowvoltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT240 and LVTH240 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation. ■ ■ ■ ■ ■ ■ 5V VCC Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH240), also available without bushold feature (74LVT240) Live insertion/extraction permitted Power Up/Down high impedance provides glitch-free bus loading Outputs source/sink –32mA/+64mA Functionally compatible with the 74 series 240 Latch-up performance exceeds 500mA ESD performance: – Human-body model > 2000V – Machine model > 200V – Charged-device model > 1000V Ordering Information Order Number 74LVT240WM 74LVT240SJ 74LVT240MSA 74LVT240MTC 74LVTH240WM 74LVTH240SJ 74LVTH240MSA 74LVTH240MTC Package Number M20B M20D MSA20 MTC20 M20B M20D MSA20 MTC20 Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Shrink Small Outline Package (SSOP), JEDEC MO-150, 5.3mm Wide 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 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Shrink Small Outline Package (SSOP), JEDEC MO-150, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Device also available in Tape and Reel.
