74ABT2541
Octal Buffer/Line Driver with
25Ω Series Resistors in the Outputs
General Description
The ABT2541 is an octal buffer and line driver designed to
drive the capacitive inputs of MOS memory drivers,
address drivers, clock drivers, and bus-oriented transmit-
ters/receivers. Functionally identical to the ABT541.
The 25Ω series resistors in the outputs reduce ringing and
eliminate the need for external resistors.
Features
s Guaranteed output skew
s Guaranteed multiple output switching specifications
s Output switching specified for both 50 pF and
250 pF loads
s Guaranteed simultaneously switching noise level and
dynamic threshold performance
s Guaranteed latchup protection
s High impedance glitch free bus loading during entire
power up and power down cycle
s Nondestructive hot insertion capability
s Disable time less than enable time to avoid bus
contention
