74F2240 Octal Buffer/Line Driver
January 1995 Revised May 1999
74F2240 Octal Buffer/Line Driver with 25 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 25 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 25 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
