74F2240

74F2240 Octal Buffer/Line Driver January 1995 Revised May 1999 74F2240 Octal Buffer/Line Driver with 25Ω Series Resistors in the Outputs General Description The 74F2240 is an inverting octal buffer and line driver designed to drive capacitive inputs of MOS memory devices, address and clock lines or act as a low undershoot general purpose bus driver. The 25Ω series resistor in the outputs reduces undershoot and ringing and eliminates the need for external resistors. Features s 3-STATE outputs drive bus lines or buffer memory address registers s Outputs sink 12 mA and source 15 mA s 25Ω series resistors in outputs eliminate the need for external resistors s Designed to drive the capacitive inputs of MOS devices s Guaranteed 4000V minimum ESD protection Ordering Code: Order Number 74F2240SC 74F2240QC Package Number M20B V20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 20-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.350 Square Devices also available in Tape and Reel.
