74ABT2541

Octal Buffer/Line Driver with

25

Ω 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 25

Ω 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

Ordering Code:

Devices also available in Tape and Reel. Specify by appending “X” to the ordering code.
