The 25 Ω 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 Ω 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: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
