74FR2244 Octal Buffer/Line Driver
June 1991 Revised August 1999
74FR2244 Octal Buffer/Line Driver with 25Ω 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 25Ω series resistors in outputs eliminate the need for external resistors s Designed to drive the capacitive inputs of MOS devices
