74FR2244 Octal Buffer/Line Driver June 1991 Revised August 1999 74FR2244 Octal Buffer/Line Driver with 25 Series Resistors in the Outputs General Description The 74FR2244 is a non-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. 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 Ordering Code: Order Number 74FR2244SC 74FR2244SJ 74FR2244PC Package Number M20B M20D N20A 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 Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
