74LVX240MX

Revised October 2003 74LVX240 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs General Description Features The LVX240 is an octal inverting buffer and line driver designed to be employed as a memory address driver, clock driver and bus oriented transmitter or receiver which provides improved PC board density. The inputs tolerate up to 7V allowing interface of 5V systems to 3V systems. ■ Input voltage translation from 5V to 3V ■ Ideal for low power/low noise 3.3V applications ■ Guaranteed simultaneous switching noise level and dynamic threshold performance Ordering Code: Order Number Package Number 74LVX240M 74LVX240SJ 74LVX240MTC Package Description M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation.
