Overview
74F2244 Octal Buffer/Line Driver with 25Ω Series Resistors in Outputs October 1988 Revised March 1999 74F2244 Octal Buffer/Line Driver with 25Ω Series Resistors in Outputs General Description The F2244 is an octal buffer/line driver designed to drive the capacitive inputs of MOS memory drivers, address drivers, clock drivers and bus-oriented transmitters/receivers.
The 25Ω series resistors in the outputs reduce ringing and eliminate the need for external resistors.
Features s 3-STATE outputs drive bus lines or buffer memory address registers s 12 mA source current 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 74F2244SC 74F2244MSA 74F2244PC Package Number M20B MSA20 N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.
