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
a73 Guaranteed output skew
a73 Guaranteed multiple output switching specifications
a73 Output switching specified for both 50 pF and
250 pF loads
a73 Guaranteed simultaneously switching noise level and
dynamic threshold performance
a73 Guaranteed latchup protection
a73 High impedance glitch free bus loading during entire
power up and power down cycle
a73 Nondestructive hot insertion capability
a73 Disable time less than enable time to avoid bus
contention
Ordering Code:
Devices also available in Tape and Reel. Specify by appending “X” to the ordering code.
