74ABT2244 Octal Buffer/Line Driver with 25Ω Series Resistors in the Outputs tm Features General Description ■ Guaranteed latchup protection The ABT2244 is an octal buffer and line driver designed to drive the capacitive inputs of MOS memory drivers, address drivers, clock drivers, and bus-oriented transmitters/receivers. ■ High-impedance, glitch-free bus loading during entire power up and power down cycle ■ Nondestructive, hot-insertion capability The 25Ω series resistors in the outputs reduce ringing and eliminate the need for external resistors.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol Parameter VCC Conditions Min.
